Officers of the Tax Agency’s customs surveillance unit and the Civil Guard’s organised-crime and drugs team dismantled an indoor cannabis network based in the provinces of Zaragoza and Huesca in an operation the agency announced on 19 September 2025.[1]
The investigation began in March 2023 over a villa in the Las Lomas de Gállego estate in Zuera suspected of housing an indoor grow, and uncovered a hierarchically structured organisation growing cannabis inside two rented villas while its leaders lived in the city of Zaragoza.[1] Both villas ran on electricity stolen from street lighting, with fraud later put at 160,000 euro.[1]
In the early hours of 18 June officers searched all three properties: the Banastás villa held 1,212 small plants plus drying and cultivation supplies upstairs, the Las Lomas villa held 3,070 plants at various growth stages across rooms on all three floors, and the Zaragoza flat held the organisation’s two leaders.[1] The total haul was 4,282 plants in more than ten fitted-out rooms, with 13,300 euro and 18,920 Serbian dinars in cash, phones and forged identity documents.[1]
The six detainees, five men and one woman of Serbian and Slovak nationality aged 30 to 50, face charges of criminal-organisation membership, drug trafficking and electricity fraud, with two also subject to extradition warrants; all were remanded to Zuera prison.[1] The agency said the network is considered dismantled but the investigation continues, with a further arrest and an asset inquiry under way.[1]
