A large-scale police action, carried out as part of operation Fabryka, coordinated by Europol, led to the dismantling of a criminal network operating throughout the European Union. Coordinated efforts were carried out in Poland, as well as in Belgium, Germany and the Netherlands. These actions targeted a network suspected of importing large quantities of precursors used for the production of synthetic drugs in laboratories across several countries.

In addition, the network was involved in money laundering activities to promote its illicit operations. During the course of the investigation, law enforcement authorities determined that the network may have imported over 1,000 tonnes of precursors, enough to produce more than 300 tonnes of synthetic drugs such as MDMA, amphetamine and cathinone.
It is estimated that illegal activities generate billions in criminal profits for the criminal networks involved. The criminal assets flow into the legal economy, creating significant risks of market distortion, unfair competition, and systematic infiltration of legitimate businesses by organised crime.
The investigation began in 2024 based on intelligence shared by the Polish police, specifically by the Drug Crime Unit of the Wrocław Provincial Police Headquarters. The information provided by the police officers from Lower Silesia was critical to initiating the case and facilitating subsequent international cooperation within the taskforce. Between February 2025 and January 2026, more than 20 action days were carried out targeting connected criminal groups, their production facilities, and storage sites across Europe. The operation culminated in a coordinated action day against the alleged wholesale network responsible for the importation and distribution of chemical precursors.
This network was responsible for the importation, repackaging, and distribution of precursors used in the production of synthetic drugs. Chemicals, originating from China and India, entered the EU through various countries and were transported to Poland for repackaging and subsequent distribution in illegal laboratories across the EU. Since the start of the investigation in 2024, Europol supported action days aimed at different cells of the network, as well as connected groups involved in the production of synthetic drugs in laboratories.
The overall results from all action days (from February 2025 to January 2026) include more than:
• 20 action days: 85 arrests; 100 searches; as well as: 50 delivery points identified; 24 industrial-scale laboratories dismantled; 16 storage locations found; multiple seizures:
- About €500,000 in cash.
- 3,559 kilograms and 982 litres of drugs (including 4-CMC, cathinone, MDMA, amphetamine oil).
- More than 120,000 litres of toxic chemical waste.
- 1,000 tons of precursors (chemicals used for the production of synthetic drugs).
The operational structure of this criminal network was complex, with seven legitimate companies in Poland facilitating import and distribution activities, and a high-level leadership coordination connecting the various criminal groups from EU countries.
In some cases, the criminal cells operating within the broader network managed both the logistics for the supply of precursors and the coordination of production in clandestine laboratories. The main criminal network targeted by this investigation is predominantly composed of Polish nationals, with the involvement of some Belgian and Dutch citizens operating within interconnected groups.
