This section provides that if any person is detained or transferred to a police station under this Part, the person is to be treated as having been arrested elsewhere and brought to the station for the purposes of Article 55 of PACE, which provides constables with powers to search arrested persons at police stations. A constable can avail of these powers in respect of a person detained at a place of safety under this Part. This section also provides for a modification of Article 55 of PACE so that it can apply in these circumstances.
