A major international police operation against gangs on the dark web led to the arrest of 354 people in 14 countries, with authorities seizing more than 5.8 tons of drugs, 152 firearms and €150 million worth of cash and cryptocurrencies.
Operation TorNado, coordinated by Europol, ran from May 2025 to October 2026, with the majority of arrests made in the United States and four European countries. Hundreds of police operations were carried out worldwide as part of Operation TorNado, which aimed to combat drug trafficking and other criminal activities via the so-called “dark web”.
The results of the month-long investigation were announced on Thursday by US and European officials, presenting the report of international cooperation coordinated by Europol, the European Union's law enforcement agency.
The operation involved police services from 14 countries, including Australia, the United States, Britain, France and Germany.
Where did most of the arrests take place?
Of the total 354 arrests, the majority took place in the US, where 132 people were arrested.
The UK followed with 59 arrests, Hungary with 45, Germany with 41 and France with 23.
These five countries accounted for 300 of the 354 arrests, while the rest were made in other states that participated in the operation.
Over 5.8 tons of drugs and 150 million euros in cash and cryptocurrencies
The quantities of illegal substances identified during the investigations were particularly large.
In Europe, police seized almost a ton of narcotics, mainly amphetamines, ketamine, MDMA, cocaine and cannabis.
In the United States, according to Europol, more than 4.8 tons of drugs, 152 firearms, as well as cash and cryptocurrencies with a total value of 150 million euros were seized.
Despite the scale of police operations, the European agency warned that illegal online markets are still adapting to law enforcement interventions.
"The operation highlighted the emerging resilience of dark web markets, which continue to adapt despite disruptions," he said in a statement.
FBI: Targeting trafficking of fentanyl and other deadly drugs
FBI Deputy Director Christopher Raya emphasized the importance of the operation in combating fentanyl trafficking.
"Operation TorNado addressed one of the most urgent threats of our time: the trafficking of fentanyl and other deadly drugs through the dark web," he said.
The US official stressed that the investigations were not limited to identifying individual users, but also targeted key players in the illegal networks.
"We identified the main sellers on the dark web," he noted, adding that law enforcement agencies were able to dismantle critical parts of the circuits that allowed them to continue their activities.
