Cross-border enforcement
Section 136 of the Criminal Justice and Public Order Act 1994 ("the 1994 Act") provides that, where a warrant for the arrest of a person has been issued in any of the jurisdictions of England and Wales, Northern Ireland and Scotland, the person can be arrested in any other jurisdiction by a police officer from either the jurisdiction where the offence was committed or the jurisdiction in which the person is found.
	Section 137 of the 1994 Act provides that a constable from one jurisdiction can, without a warrant, arrest (or in the case of Scottish constables, "detain") a person in a jurisdiction other than their own 'home' jurisdiction, if that constable has reasonable grounds for suspecting that the person has committed or attempted an offence in the constable’s 'home' jurisdiction.
	Section 140 of the 1994 Act provides that a constable from one jurisdiction who is present in another jurisdiction can, without a warrant, arrest a person in that other jurisdiction in respect of an offence committed there. Arrest would be on the same basis as a constable who is from that other jurisdiction
