Cumbria Police has arrested three people and seized 1,646 suspected cannabis plants from a building in Egremont.
Officers seized the plants from across 23 rooms after executing a misuse of drugs warrant today, Tuesday October 12.
The find was made this morning after officers carried out the warrant in Bookwell at 8.35am.
Three men were all arrested on suspicion of cultivation of cannabis and remain in custody this evening.
Detective Inspector Hayley Wilkinson said: “The public are likely to see a larger-than-normal police presence around this property as our enquiries continue.
“We take all suspected drugs cultivation seriously and would continue to urge anyone who has any suspicions about any buildings that might be used for illegal purposes to come forward with information.”
