Arrest 逮捕
An arrest is the act of depriving people of their liberty, usually in relation to an investigation or prevention of a crime, and thus detaining the arrested person in a procedure as part of the criminal justice system.
Police and various other bodies have powers of arrest. In some places, the power is more general; for example in England and Wales, any person can arrest "anyone whom he has reasonable grounds for suspecting to be committing, have committed or be guilty of committing an indictable offence," although certain conditions must be met before taking such action.
