According to local media, the Dutch Fiscal Information and Investigation Service in conjunction with the Department of Public Prosecutions launched 15 raids all across the country. Ten people were detained, zdnet.com reports.
Police had received information from Dutch banks about large amounts of money being cashed through ATMs. In the raids, police seized cash, luxury cars and chemical substances which are used to produce the drug ecstasy.
It is believed that the men, some of whom are Lithuanian and Moroccan, have been operating on the deep web – a normally invisible part of the internet in which underground markets are thriving.
Bitcoins are used to help conceal transfers and ensure anonymity of both buyers and sellers and are often used on the deep web.
The Dutch police coordinated with law enforcement agencies from the United States, Australia, Lithuania and Morocco in organising the raids.
