The Dutch Fiscal Investigation and Information Service (FIOD), a special law enforcement agency assigned to investigate tax fraud, is also interested in combatting money laundering. Knowledge about money laundering techniques and forfeiture procedures are integrated in the basic training of all investigating officers. The FIOD cooperates with other police organizations in organized crime investigations and also conducts its own independent investigations. Financial expertise is used to gather, check, refine, process, and analyze financial information. Financial investigations have the following objectives: generating tactical information for investigations; determining the volume of the unlawfully obtained assets; tracing assets of criminals and/or criminal organizations; and confiscating the unlawfully obtained assets. The European Financial Action Task Force (FATF) developed 44 recommendations on money laundering agreed to by the member countries. This article presents a few of the FATF recommendations that focus on internal corporate controls, particularly those that have to do with financial institutions and the disclosing of the identity of clients. The usefulness of financial investigative techniques in the fight against money laundering and related organized crime is illustrated in the Kolibri investigation. Their use in the fight against organized business crime is also outlined. 1 reference
