The criminal network ran plantations in the Spanish regions of Zaragoza and Tarragona, where fellow nationals were exploited for the cultivation of narcotics, Eurojust, which supported the operation, said in a statement Thursday.
Police dismantled 14 indoor plantations, including one “hidden under a Russian orthodox church.”
The network had established a sophisticated distribution chain, using lorries registered in the names of businesses that had been set up in other EU countries, according to the agency.
Eurojust said that law enforcement agencies carried out 19 searches and seized over 17,000 marijuana plants, more than 880 kilograms of marijuana buds, and at least 130 kilograms of produced marijuana and hashish resins during a major action day in June. Some 400 kilograms of marijuana and nearly four kilos of hashish had already been captured in January.
Police have also seized around 250,000 euro (US$294,263) in cash, a luxury car, computer and telecommunication equipment and some weapons.
The criminal group was well-structured and used electricians to condition and manage the plantations, according to Eurojust. It also engaged managers and middlemen between its various echelons, as well as attorneys, to open accounts using fraudulent papers.
“Most of the proceedings were laundered in Serbia, Spain and other European countries, using a string of shell companies,” The Hague-based EU Agency for Criminal Justice Cooperation said.
It also said that the key suspects “will be charged with drug trafficking, migrant smuggling, and money laundering.”
