Sgt Dave Perkins, who led the operation, said: "We are very pleased that we have prevented such a large amount of drugs from reaching the streets."

"The offenders had also illegally by-passed the electricity supply when setting up the factory, creating a potential fire hazard and putting innocent lives in danger," he added.
