After the Wall Street Market was rolled up on the dark web in 2019, a total of 179 sellers were arrested, police announced on Tuesday.
Eight people have been arrested in the Netherlands.
More people may be arrested because the investigative services are still trying to find out the identity of sellers.
In May 2019, it became known that European authorities had taken over the marketplace, where mainly drugs were traded.
Wall Street Market was one of the largest remaining platforms on the dark web after the disappearance of other trading places.
The dark web is a part of the internet that cannot be reached with regular browsers.
With the special Tor browser, which protects the identity of users, these websites can be visited.
This part of the internet is not only used for illegal activities.
Activists and journalists, among others, use the dark web to remain anonymous and to prevent opposition by oppressive regimes.
When the international operation against Wall Street Market was announced, the Dutch police announced that at least two hundred Dutch people were active on the marketplace.
In total, 5,000 drug sellers are said to have used the site.
