Money laundering (criminal property offences)
Investigation — Authorised Professional Practice
Summary
This APP topic outlines the fundamentals of investigating money laundering, detailing how funds derived from crime are transferred through various means by criminals. It emphasizes the importance of understanding the impact of money laundering on crime profitability, its threat to financial systems, and the criminal acts defined under the Proceeds of Crime Act 2002 (POCA). The document serves as a guide for police officers on how to approach investigations into money laundering, including appropriate strategies, the necessity for effective intelligence gathering, and the considerations for applying specific money laundering charges.

- 5Foster cooperation with Financial Investigation Units and asset recovery teams.

- Knowledge
