Europol today announced it dealt a double blow to dark web marketplaces after taking down both the Wall Street Market and Silkkitie, aka The Valhalla Marketplace.

The Wall Street Market was considered the second largest illegal online market on the dark web with more than 1,150,000 customer accounts and more than 5,400 sellers registered.

The alleged marketplace officials who are said to have received commission payments of 2 to 6 percent of the sales  were arrested in Germany while two of the highest selling suppliers of narcotics were arrested in the U.S. and Finnish authorities took down Silkkitie earlier this year, according to a May 3 press release.

Authorities seized over €550 000 in cash, alongside cryptocurrencies Bitcoin and Monero in 6-digit amounts, several vehicles and other evidence including computers and data storage.

The takedown efforts were supported by the Dutch National Police, Europol, Eurojust and various U.S. government agencies, including the Drug Enforcement Administration, Federal Bureau of Investigation, Internal Revenue Service, Homeland Security Investigations, US Postal Inspection Service, and the US Department of Justice.
