Police around the world have arrested 150 suspects in one of the largest-ever dark web sting operations.
The suspects arrested included several high-profile targets, involved in buying or selling illegal goods online, Europol said today.
Operation Dark HunTOR also recovered millions of pounds in cash and bitcoin, darknet market markets onion address as well as drugs and guns.
The bust stems from a German-led police sting earlier this year taking down the 'world's largest' darknet marketplace.
Darknet markets are e-commerce sites designed to lie beyond the reach of regular search engines and are popular with criminals, as buyers and sellers are largely untraceable.

Dark HunTOR, 'was composed of a series of separate but complementary actions in Australia, Bulgaria, France, Germany, Italy, the Netherlands, Switzerland, the United Kingdom, and the United States,' the Hague-based Europol said.
In the United States alone, darknet market lists police arrested 65 people, while 47 were held in Germany, 24 in Britain, and four each in Italy and the Netherlands, among others.
A number of those arrested 'were considered high-value targets' by Europol.
Law agents also confiscated 26.7 million euros (£22.45million) in cash and virtual currencies, as well as 45 guns and 516lbs of drugs, including 25,000 ecstasy pills.
Italian police also shut down the 'DeepSea' and 'Berlusconi' marketplaces, 'which together boasted over 100,000 announcements of illegal products', said Europol, which coordinated the operation together with its twin judicial agency Eurojust.
German police in January closed down the 'DarkMarket' online marketplace, used by its alleged operator, an Australian, to facilitate the sale of drugs, stolen credit card data and malware.
Europol said the arrest of the alleged operator, caught near the German-Danish border at the time, and the seizure of the criminal infrastructure provided 'investigators across the world with a trove of evidence'.
German prosecutors at the time said DarkMarket came to light in the course of a major investigation against the web-hosting service Cyberbunker, located in a former NATO bunker in southwest Germany.
Europol's European Cybercrime Centre EC3 has since been compiling intelligence packages to identify the key targets, the continent's policing agency said.
The secret 'darknet market' includes websites that can be assessed only with specific software or authorisations, ensuring anonymity for users.
