The Code of Practice to the Criminal Procedure and Investigations Act 1996 (CPIA) defines a criminal investigation as:
An investigation conducted with a view to it being ascertained whether a person should be charged with an offence, or whether a person charged with an offence is guilty of it.
This will include-
- investigations into crimes that have been committed;
- investigations whose purpose is to ascertain whether a crime has been committed, with a view to the possible institution of criminal proceedings; and
- investigations which begin in the belief that a crime may be committed, for example when the police keep premises or individuals under observation for a period of time, with a view to the possible institution of criminal proceedings
An investigator may be a warranted officer or member of police staff. Section 38 of the Police Reform Act 2002 allows chief officers to designate police staff as investigating officers.
The Professionalising Investigation Programme (PIP) provides a structured development programme to embed and maintain investigative skills for police officers and police staff. It aims to deliver the capability to conduct professional investigations at all levels within the Police Service and in other sectors of Law Enforcement.
