The FIOD-ECD (Fiscale Inlichtingen en Opsporingsdienst- Economische Controledienst) is the finance ministry’s special investigations unit. As well as dealing with tax fraud, the agency investigates bankruptcy, fraud and money laundering. And, says its website, it ‘contributes to the fight against organised crime and terrorism by mapping out money flows of criminal and terrorist organisations’, often together with a sister organisation abroad.
