493.This section applies if a person has been arrested at a police station, taken to a police station after arrest or detained after arrest in an extradition case. For such cases the Secretary of State can apply by order the four specified sections of PACE or, as appropriate, the corresponding Northern Ireland provisions (subsection (2)). These are listed in subsections (3) and (4) and determine the rights of an arrested person at a police station in relation to searches, the right to inform someone of the arrest and the right to have access to legal advice.
