Two officers on patrol in Fordham Road, Soham, smelled cannabis at about 11pm on 28 May 2014 and followed the scent to a warehouse on Regal Drive, where they forced entry and found one of the biggest cannabis factories ever discovered in Cambridgeshire.[1][2] Inside the former Garner Plastics unit, officers found about 7,000 growing plants as well as 400 drying plants and 5,000 root balls, headlined as 12,000 plants.[2] Detective Inspector Dave Murphy called it a significant seizure on an industrial scale.[2] Police put the potential yield at anywhere from £2 million to £6 million.[1][2]

Two men were inside the warehouse but broke free through a window and fled; one was later arrested, taken to Parkside police station in Cambridge, and bailed to return on 24 July.[1][2] The factory was believed to have been running for about a year, and the unit had been marketed for letting until June 2013.[1][2]
