Police have discovered a huge cannabis factory in a former bingo hall in Kettering.

Officers discovered 2,000 plants growing under lamps when they raided the old Gala Bingo building on the High Street on Friday morning.

Police say one harvest could yield £750,000 profit for the criminals.

There were 25 officers along with police dogs involved in the operation which was sparked by a tip-off from the public along with intelligence from community police officers and local council workers.

The hall closed down last year and the building has since been leased.

A previous factory was found in the building in February and is under investigation.

Northamptonshire Police have shared a video of their operation on social media

"This is a criminally audacious set-up especially in the middle of Kettering town centre. "The size of the building and the amount of organised effort and work that has gone into setting it up. "You might think you can get away with it but we will eventually catch-up with you." Sgt Sean Marshall, Northamptonshire Police

Police say they will destroy all the plants and all the equipment.
