The Mossos d’Esquadra, Catalonia’s regional police, dismantled one of the region’s largest indoor cannabis farms after finding 5,140 plants in an industrial warehouse in L’Hospitalet de Llobregat on 20 October 2025.[1] Police had watched the site for days after intelligence pointed to a major cultivation operation, and abnormal electricity consumption confirmed their suspicions before a judge authorised entry.[1]

Inside the 300-square-metre facility, officers found plants at an advanced growth stage alongside a separate area for drying and packaging.[1] The farm used ventilation with specialised gases to speed growth and mask odours, and the suspects had dug a 1.5-metre tunnel to tap a high-voltage line, stealing electricity valued at over 194,000 euros.[1]

Two suspects were arrested inside the warehouse during the raid, and two more alleged suppliers and logistics coordinators were detained hours later.[1] All four men, aged 27 to 30, face allegations including drug trafficking, electricity fraud, membership of a criminal organisation and document forgery.[1]
