European Police Smash Biggest-ever Synthetic Drug Network, Arrest 85 Across 6 Countries

The European police, on Wednesday, revealed that they have broken up a vast cross-border synthetic drug network in what authorities described as the largest operation of its kind, delivering a major setback to organised crime.

The year-long investigation led to the dismantling of 24 industrial-scale drug laboratories, the seizure of nearly 1,000 tonnes of chemical precursors, and the arrest of more than 85 suspects across Europe. Among those detained were two alleged ringleaders from Poland, according to Europol.

The operation involved law enforcement agencies from Belgium, the Czech Republic, Germany, the Netherlands, Poland and Spain. Europol’s head of the European Serious Organised Crime Centre, Andy Kraag, said the scale of the crackdown was unprecedented.

“This is by far the largest operation we have ever carried out against synthetic drug production and distribution,” Kraag said, describing it as a “massive blow” to criminal groups involved in the trade.

Authorities first became suspicious in 2024, when Polish police identified a network importing unusually large quantities of legal chemicals from China and India. Further investigations revealed that the substances were being repackaged and mislabelled before being distributed across the European Union to laboratories producing drugs such as MDMA, amphetamines and methamphetamine.

Most of those arrested were Polish nationals, though investigators believe Belgian and Dutch suspects were also involved.

Kraag said the operation followed a “supply-chain strategy”, aimed at cutting off criminal networks from the materials needed to manufacture synthetic drugs. “These groups no longer have their supply,” he said.

Beyond the dangers posed by drug use, Europol highlighted the broader impact of the trade, including violence, corruption and money laundering, as well as severe environmental damage. Police seized more than 120,000 litres of toxic chemical waste, which criminal groups often dump illegally on land or into waterways.

“Today it’s profit for criminals. Tomorrow it’s pollution,” Kraag warned.

Europol said investigations are continuing, stressing that while a major distributor has been taken down, other networks remain under scrutiny.
