The Proceeds of Crime Act 2002 (c. 29) (the “2002 Act”) provides for a system of accreditation for financial investigators, who are known as ‘accredited financial investigators’. The 2002 Act makes reference to accredited financial investigators throughout. The main purpose of doing so is to allow, in certain circumstances, accredited financial investigators to discharge powers or other functions which are granted to law enforcement officers (such as, for example, police constables or Serious Fraud Office officers).
