This is the dramatic moment cops used a chainsaw to smash their way into an industrial unit to uncover a massive £2.7 million cannabis factory.

Three men, aged 27, 30, and 45, were arrested after officers swooped at the lock up in Hortonwood, Telford, Shrops., in the early hours of Friday (8/11).

A total of 2,739 mature cannabis plants were discovered inside along with several boxes of already cropped plants.

West Mercia Police video footage shows how officers cut their way through a metal fence and shutters before using a battering ram to gain access to the unit.
