The Police can arrest you without the Court’s permission (i.e. a Warrant of Arrest) if they reasonably suspect you’ve committed an arrestable offence and they need to detain you to help with investigations or charge you in Court. You can find out more information about arrestable offences here in the First Schedule of the Criminal Procedure Code. If the Police reasonably suspect that you’ve committed a non-arrestable offence, they can only arrest you if they have a Warrant of Arrest.
