Arrest is a act of depriving a person of his or her liberty in response to a crime and is part of the criminal justice system.
An arrest is the act of depriving a person of his or her liberty usually in relation to the purported investigation or prevention of crime and presenting (the arrestee) to a procedure as part of the criminal justice system. The term is Anglo-Norman in origin and is related to the French word arrt, meaning 'stop'. The word 'arrest' when used in its ordinary and natural sense, means the apprehension of a person or the deprivation of a person's liberty. The question whether the person is under arrest or not depends not on the legality of the arrest, but on whether the person has been deprived of personal liberty of movement. When used in the legal sense in the procedure connected with criminal offences, an arrest consists in the taking into custody of another person under authority empowered by law, to be held or detained to answer a criminal charge or to prevent the commission of a criminal or further offence.
