Section 5: Provisional arrest
29.This section sets out the procedure for arrest where there are reasonable grounds to believe that a Part 1 warrant has been, or shortly will be, issued by a recognised authority in a category 1 territory.
30.Subsection (1) describes who may make an arrest in these circumstances. As with an arrest under section 3, a constable or a customs officer may make a provisional arrest anywhere in the United Kingdom. A service policeman may arrest a person who is subject to the relevant service law, in a place where he would have the authority to arrest that person under that law (subsections (2) to (5)).
