Charged with Mischief in Singapore: What are the Penalties?

Last updated on July 17, 2025

Mischief encompasses a broad spectrum of offences that involve causing wrongful loss or damage to another person’s property or to public property. The severity of punishment for such offences varies and is determined by several key factors, including the extent and nature of the damage caused, whether the act was committed impulsively or with premeditation, the potential or actual harm to public safety or interest, and whether the offence disrupted essential services or endangered others.

As the nature of mischief and the corresponding punishment can vary significantly depending on the circumstances, this article will explore the following:

What is Mischief?

Mischief, as defined in the Penal Code, refers to an act that results in the reduction of value or utility or destruction of property. In doing the act, the perpetrator must have intended to cause, or knows he is likely to cause, wrongful loss or damage to the public or another person.

Examples of acts of mischief include burning a security that belongs to another party, throwing a valuable and expensive item such as a ring that belongs to someone else into a river or shooting a horse that you may have joint property over with someone else.

For an act to constitute as mischief under the Singapore Penal Code, two elements must be proven:

There must be an act that causes destruction of any property, or diminishes the value or utility of the property or affects it injuriously
There must be an intention to cause, or knowledge that one is likely to cause, wrongful loss or damage to the public or any person

These elements can be manifested in various ways. For example, in one incident, a married couple was charged with one count of mischief after they poured coffee on a lion dance costume that was to be used in a championship performance. They were reportedly upset about their son’s involvement with the troupe and did not want him to participate in the competition. Their actions disrupted the event and resulted in damage to the costume, as it was stained by the coffee and cracked when the wife kicked the lion’s head. The deliberate nature of their conduct and the actual damage caused indicate a clear intent to affect the property injuriously and cause wrongful loss, thereby satisfying the elements of the offence of mischief.

What are the Penalties for Committing Mischief?

General mischief (section 426)

The punishment for general mischief, as stated in section 426 of the Penal Code, is imprisonment up to 2 years or a fine, or both.

In the case of the married couple discussed above, the husband was fined $3,000 after pleading guilty to one count of mischief, while his wife was fined $4,000 for one count of mischief and another unrelated charge. Both of them also paid $665 each in restitution to the lion dance troupe to cover the cost of the damaged costume.

Other Types of Mischief Offences in Singapore and Their Penalties

Besides general mischief under section 426 of the Penal Code, there are also 8 specific forms of mischief which are defined under the Penal Code. These categories of mischief attract different penalties and consequences as they are more serious forms of mischief.

1. Mischief causing disruption to key service (section 427)

An act of mischief that disrupts key services, or interferes with the performance of duties or the exercise of powers by the Government or a public agency, may result in imprisonment for up to 10 years, a fine, or both.

Key services refer to essential services such as public utilities, emergency response, financial systems, public healthcare, public transport, and the reliable and safe supply of food. A public agency includes any corporate or unincorporated body established by public law to perform public functions, or any department or Ministry of the Government or an Organ of State.

In September 2021, a man was sentenced to 24 weeks’ jail after he assaulted a bus driver who told him to cover his nose and mouth with the mask he had tucked under his chin. His total sentence was an accumulation of 3 charges, which included one count each of assault, harassment and committing an act of mischief that caused disruption to a key service, which was public transport in this case. The charge of mischief arose from the accused’s act of pulling the bus control lever and causing disruption to the bus service. The bus driver had to stop the bus to tell the accused to remain seated, as he was verbally abusing the bus driver with vulgarities. This incident shows that acts of mischief can be typically coupled with other charges, which will increase the overall sentence of the accused.

2. Mischief by killing or maiming any animal (section 428)

Anyone liable for killing, poisoning or maiming or rendering useless any animal may result in imprisonment for up to 5 years, a fine, or both.

A man was sentenced to a fine of $1,000, under a section 428 charge after he kicked the complainant’s dog in its stomach, causing its death. The situation unfolded when the complainant and the accused were walking their respective dogs. When the complainant unleashed his 3 dogs, they surrounded the accused and his dog, and one of them bit the accused’s dog. The accused proceeded to kick the complainant’s dog in the stomach out of anger, causing the dog to die from a ruptured liver.

It is interesting to highlight that the judge was sympathetic to the accused as well, and noted that the complainant was also to blame for his own dog’s death as he failed to keep all his dogs on leash at all times, and allowed them to rush across the road to attack the accused’s dog. As this case was not one of calculated cruelty to kill an animal, and the complainant’s thoughtlessness also contributed to the situation, the judge stated that a custodial sentence was not appropriate.

3. Mischief by fire or explosive substance with intent to cause damage (section 435)

A person who commits mischief by fire or using any explosive substance, with the intent to cause, or knowing it is likely to cause damage to property, will be liable to punishment by imprisonment for up to 7 years and a fine.

In March 2025, a man who was allegedly linked to a series of fires in Woodlands was charged with one count of committing mischief by fire. The first two incidents involved the burning of items placed on a bench, while the other two involved the contents of a recycling bin, where the accused allegedly threw an unknown object that ignited a fire. The resulting damage included melted bins, soot-covered walls, and a lingering smell of smoke at the HDB void deck.

4. Mischief by fire or explosive substance with intent to destroy a house, etc. (section 436)

Anyone who commits mischief by fire or any explosive substance, intending to cause, or knowing it to be likely that he will thereby cause, the destruction of any building which is ordinarily used as a place for:

Worship
The administration of justice
The transaction of public affairs
Education
Art
Public use or ornament
Human dwelling
Custody of property,

will be punished with imprisonment for life, or with imprisonment for a term which may extend to 10 years, and also be liable to a fine.

5. Mischief with intent to destroy or make unsafe a decked vessel or a vessel of 20 tons burden (section 437)

Any person who commits mischief against a decked vessel or a vessel with a burden of 20 tons or more, with the intent to destroy or render it unsafe, or knows it is likely to do so, will be liable to imprisonment for up to 10 years and also be fined.

For example, a person who sneaks onto a large cargo ship and damages part of its engine, intending for it to break down at sea, can be charged under section 437 for mischief with intent to destroy or make the vessel unsafe. Even if the damage is found before the ship leaves, he will still be charged, as his actions would have compromised the ship’s safety.

6. Punishment for the mischief described in section 437 when committed by fire or any explosive substance (section 438)

Anyone who commits or attempts to commit by fire or any explosive substance the offence of mischief described in section 437, will be liable to imprisonment for life, or with imprisonment for a term which may extend to 10 years. Where he is not sentenced to imprisonment for life, he will also be liable to a fine.

For example, any harm caused to a ship or vessel (weighing 20 tons or more) using fire or explosives, such as setting a fire, planting an explosive device, or throwing a petrol bomb onto or near the vessel, may amount to an offence under section 438 of the Penal Code. Even if the attempt fails or results in only minor damage, the act is treated with utmost seriousness due to the significant risk it poses to life and property.

7. Punishment for intentionally running vessel aground or ashore with intent to commit theft, etc. (section 439)

Any person who intentionally causes a vessel to run aground or ashore with the intent to commit theft of property on board, or to dishonestly misappropriate such property, will be punished with imprisonment for up to 10 years and also be fined.

Such a charge may arise where a crew member on a cargo ship deliberately steers the vessel off course and runs it aground near a remote beach, intending to steal valuable goods from the cargo hold and escape with them.

8. Mischief committed after preparation made for causing death or hurt (section 440)

Anyone who commits the mischief of preparing to inflict death, bodily harm, or wrongful restraint to a person, or causing a person to fear death, bodily harm, or wrongful restraint, will be liable to imprisonment for up to 5 years, and also be liable to a fine.

For example, this charge may arise where a person secretly prepares to damage someone’s car by tampering with the brakes, intending to cause an accident that could seriously injure or kill the driver. Even if no accident happens, this act of preparation to cause harm can lead to a charge under section 440 of the Penal Code.

Is Mischief an Arrestable Offence?

A general act of mischief is not an arrestable offence, meaning that the police may not arrest the alleged offender without a warrant. In order to make an arrest, the police will have to investigate the matter and obtain an arrest warrant from the court.

However, where the act of mischief is more severe and falls under any of these categories, they are arrestable offences, meaning that the police may arrest the alleged offender without obtaining a warrant:

Mischief, and thereby causing disruption to key service, etc.
Mischief by killing, poisoning, maiming or rendering useless, any animal
Mischief by fire or explosive substance
Mischief by fire or explosive substance with intent to destroy a house, etc.
Mischief with intent to destroy or make unsafe a decked vessel or a vessel of 20 tons burden
The mischief described in section 437 when committed by fire or any explosive substance
Running a vessel ashore with intent to commit theft, etc.
Mischief committed after preparation made for causing death or hurt, etc.

How are Offenders Sentenced for Mischief Offences?

Sentencing for mischief offences is highly fact-specific and depends on the particular circumstances of each case. In the absence of aggravating or mitigating factors, a fine is typically imposed, where the damage to property is minimal and easily remedied.

Key considerations influencing the sentence include:

Financial loss suffered by the victim
Whether the act was impulsive or premeditated
The risk of personal injury
The manner in which the mischief was committed
The offender’s age
The prevalence of such offences
The extent and permanence of the damage, and the offender’s criminal history, particularly relating to property offences

In cases involving elements of public interest, courts have imposed more severe penalties, including custodial sentences. For example, a charge of mischief causing disruption to key public services such as public utilities, emergency response, financial systems, etc. is liable to an imprisonment term of up to 10 years compared to a charge of general mischief, which attracts an imprisonment of up to 2 years.

In the case of Public Prosecutor v Bibianna Lim Poh Suan, the court imposed a fine of $800 on the offender for throwing her parents’ helper’s mobile phone into a washing machine. As there were no significant aggravating or mitigating factors, a fine was deemed appropriate. Although the phone was still functional and had a value of only $450 (based on its purchase price), the higher fine likely reflected the court’s intention to impose a punitive measure that underscores the seriousness of tampering with another person’s property.

There could also be mitigating factors that reduce the severity of the sentencing term, such as if the offender immediately atones for his misdeeds.

In the case of Public Prosecutor v Teo Chang Heng, the offender deliberately damaged a car belonging to his spouse. The damage inflicted on the car was caused by the respondent tailgating and rear-ending the car, side-swiping it after overtaking, and then colliding into it again after making two U-turns, causing the front left wheel of the car to mount the kerb. He had done so after seeing his spouse’s boyfriend driving the car and acted out of anger.

However, he immediately pleaded guilty at the scene, called the police on himself, and voluntarily surrendered. His actions, though aggressive, were directed solely at the vehicle and did not pose a danger to other road users. He was also a first-time offender with an otherwise clean record. Taking these mitigating factors into account, the court granted him a Community-Based Sentence (CBS), which allows suitable offenders to undergo community-based rehabilitation. His prompt acceptance of responsibility demonstrated his potential for rehabilitation and reintegration, and he was thus sentenced to a 120-hour Community Service Order (CSO). Nevertheless, in view of the seriousness of the offence, a 10-day Short Detention Order (SDO) was also imposed to underscore that such conduct cannot go unpunished. An SDO requires the offender to be detained in prison for a period of up to 14 days. It acts as a deterrent by allowing the offender to experience prison life without leaving a criminal record.

Will People Convicted of Mischief Have a Criminal Record?

People who are convicted of general mischief under Section 426 will not have a criminal record.

However, the following categories of mischief are registrable crimes in Singapore, meaning that it will result in a criminal record:

Committing mischief causing disruption to key service, etc.
Mischief by killing or maiming any animal
Mischief by fire or explosive substance
Mischief by fire or explosive substance with intent to destroy a house, etc.
Mischief with intent to destroy or make unsafe a decked vessel or a vessel of 20 tons burden
The mischief described in section 437 when committed by fire or any explosive substance
Running a vessel ashore with intent to commit theft, etc.
Mischief committed after preparation made for causing death or hurt, etc.

However, you might still have the opportunity to have your criminal record treated as spent after a certain period of time. This simply means that your record will be wiped clean.

To qualify for having your record spent, you must remain crime-free for at least 5 consecutive years, starting from the date of your release from prison, or from the date that your sentence was passed if you were given a fine or from the date of your remission, commutation or substituted sentence.

“Crime-free” means you must not have been:

Convicted of a registrable crime;
Unlawfully at large in relation to any registrable crime;
Detained or subject to police supervision under section 30(1) of the Criminal Law (Temporary Provisions) Act; and
Subject to a supervision order or admitted to an approved institution under the Misuse of Drugs Act or admitted to an approved centre under the Intoxicating Substances Act.

Once you accomplish this, your record will be spent automatically, and you will be able to legally declare that you do not have a criminal record.

In conclusion, committing mischief can lead to a range of penalties, including fines and/or imprisonment. More serious forms of mischief that pose danger to the public, such as those involving fire, explosives, or disruption to essential public services, typically carry harsher penalties. In determining the appropriate sentence, the courts will take into account specific factors of the case, including the nature of the act, the extent of the damage, and any history of similar offences.

Ultimately, mischief is not a trivial offence, and sentencing is carefully calibrated to reflect both the seriousness of the harm caused and the offender’s degree of culpability. In more severe cases, a conviction for mischief may result in a criminal record, which can have long-term consequences for the offender’s personal and professional life. Such a record typically remains for at least five consecutive years without any further offences before it can be expunged, underscoring the lasting impact that a mischief conviction can have beyond the immediate sentence.

Hence, before engaging in any act that could be construed as mischief, it is important to fully understand the potential legal consequences, as even seemingly minor acts can lead to serious penalties and prolonged repercussions.

If you have been charged with mischief, it is crucial to seek the advice of a criminal lawyer promptly. A criminal lawyer can help explain the charges against you and guide you through the legal process. They can also assist in building a strong defence, and advising on possible outcomes to help you make informed decisions.
