Sometimes the police can arrest you without a warrant. Here are some examples of when this can happen:

• If you escape, or try to escape, after the police arrested you earlier
• If the police catch you while you are committing a crime
• If the police think you committed a serious crime like murder, rape, serious assault, housebreaking
• If the police think you committed a drug or liquor offence
• If the police find you at night, doing something that makes them think that you are about to commit a crime or have already committed a crime
• If the police think you have not paid a fine which a court ordered you to pay
• If you try to stop the police from doing their duty
• If the police think you have guns or ammunition without a licence
• If you are carrying any other dangerous weapon and you can’t give a good reason to the police
• If the court said you must go to prison for certain periods, for example every weekend, and you do not go
• If the police think you broke the conditions of a suspended sentence
