The Netherlands plays a big role in money laundering in the European Union, according to Europol. In 2014, over a quarter of suspicious bank transactions in the EU were reported by Dutch banks, the Telegraaf reports.

The banks in Europe reported almost a million transactions they suspected involved money laundering in 2014. Dutch banks reported 277 thousand suspicious transactions. Only Great Britain reported more, with 350 thousand. 

According to Europol, the police only investigated about 1 in 10 of the reported transactions. The organization, which is a cooperation of police in all EU countries, calls on the authorities to investigate more reports of possible money laundering practices.
