Three men have been arrested after police raided what is believed to be one of the biggest ever cannabis farms found in Lancashire in the UK.
Officers discovered the cannabis in units at the Apex Trading Estate, Lower Eccleshill, Darwen at about 10am yesterday.
There were an estimated 8,000 to 10,000 plants inside at various stages of growth, Lancashire Police said.
The estimated street value of the plants runs into the millions of pounds.
Two men aged 24 and one aged 31 were arrested on suspicion of cultivation of cannabis and remain in custody.
Investigations are on-going.
A police spokesman said: “We will continue to target those taking part in this illegal activity and will act on information passed to us to disrupt and ultimately prevent those involved in the drugs trade from operating on our streets.
“Cannabis can have lasting physical and mental health effects on users as well as having a negative effect on our communities and fuelling other crime and we are determined to tackle that.
“We need the public to continue to work with us to help us tackle drug crime by informing us of any suspicious activity.”
The estimated street value of the haul is not yet known, but the force said it was their largest seizure since a £3m seizure in Fleetwood in 2018.
The Lancashire Post reported that the electricity supply is also believed to have been bypassed, and electricians will be brought in to make the premises safe before the facility can be torn down.
