The power of arrest is a mandate given to certain members of a society by the central authority that allows them to remove a criminal or suspected criminal's liberty. Arrest usually leads to custody. In almost all jurisdictions, certain people are specifically assigned to law enforcement (the police), and these people use their power of arrest frequently.
