He was part of a joint operation called Dark HunTOR, and the suspects were arrested in the United States, the United Kingdom, the Netherlands, Australia, Bulgaria, France, Germany, Italy and Switzerland.
"At that time, the German authorities arrested the alleged operator of the market and seized the infrastructure, providing researchers from around the world a collection of evidence," Europol officials said today.
The data shared with other law enforcement agencies as part of Operation Dark HuntOR, which DOJ Deputy Attorney General Lisa Monaco described at a news conference today as "the largest law enforcement operation in the world."
Monaco also said most of the suspects arrested today were drug dealers selling or buying opioids from DarkMarket.
Following the arrests, authorities reported seizing more than 26,7 million euros in cash and virtual currency, 234 kilograms of drugs and 45 firearms. The drugs seized include 152kg of amphetamine, 27kg of opioids and over 25.000 pills of ecstasy.
Both markets had over 100.000 listings for illegal products. Italian officials say they have arrested four administrators and seized 3,6m euros in cryptocurrencies.
