Right to Know Grounds of Arrest
Written in plain language for general understanding. This is educational content, not legal advice. Based on Singapore Acts of Parliament, subsidiary legislation, and official government guidance.
Singapore National Law
What is this right?
If you are arrested, the police must inform you of the grounds of arrest as soon as reasonably practicable:
- Article 9(3) of the Constitution guarantees that every arrested person shall be informed "as soon as may be" of the grounds of arrest.
- Under CPC s68, a police officer making an arrest must inform the person of the offence for which they are being arrested (unless the person is caught in the act of committing the offence).
- The officer must actually touch or confine the person unless they submit to custody by word or action.
- Arrest without warrant is permitted for seizable (more serious) offences. For non-seizable offences, a warrant is generally required.
When does it apply?
- You are being arrested by a police officer or any law enforcement officer with the power of arrest (e.g., CNB, CPIB, ICA).
- This right applies regardless of citizenship — citizens, PRs, and foreigners all have this constitutional protection while in Singapore.
What should you do?
- Stay calm and cooperate — do not resist arrest, as this is an offence under the Penal Code (s224/s225).
- If the officer does not tell you the reason, ask clearly: "What offence am I being arrested for?"
- Note the officer's name, rank, and the time of arrest.
- You may request to inform a family member or friend of your arrest — the police should facilitate this within a reasonable time.
What should you NOT do?
- Don't resist or flee — even if you believe the arrest is unlawful, resisting is a criminal offence. Challenge it later through legal channels.
- Don't make statements until you understand the allegation and have had the opportunity to consult a lawyer.
- Don't assume plainclothes officers can't arrest you — they can, but should identify themselves.
