[1] In England and Wales, the custody officer must make a decision to authorise or refuse the detention of any detainee presented before him.
This also applies to detainees presented before them by other public servants with power of arrest who may use the suite from time to time, for example revenue and customs officers and immigration officers.
The custody officer must ensure that during the whole time the person is detained at the custody suite, police officers and police staff who deal with the detained person adhere to the PACE Codes of Practice regarding the rights and treatment of persons arrested.
[1] These Codes of Practice include various requirements regarding time limits and record keeping for certain procedures that may take place whilst the person is in custody and the custody officer is responsible for ensuring these too.
If both parts of this test are satisfactory being necessary proportionate and that the subject is sufficiently identified the detention will proceed.
