Policia Nacional, Guardia Civil and Mossos d’Esquadra have seized over 50 tonnes of marijana in raids carried out on eight farms in Catalonia.
It’s the largest amount of the drug ever confiscated in a single operation.
In total, agents seized 52 tonnes of marijuana, with more than 187,000 plants and 19 tonnes of buds between June and October.
The latest raid comes hot on the heels of an earlier drugs bust where a previous record breaking 32 tonnes of canabis had been uncovered.
The drugs had an estimated street value of around €125 million.
Twenty people have been placed into custody and face charges related to the production of the illegal crop.
