The factory, containing cannabis with a street value of around £1.8 million, was discovered following further reports of suspicious activity on the airstrip. Around 2,200 plants and growing equipment were seized from the property this morning. A 29-year-old man has been arrested on suspicion of production of cannabis and a 28-year-old man has been arrested on suspicion of production of cannabis and possession of a class A drug. Both men remain in custody at Thorpe Wood Police Station. Sgt Michael Basford said: This, on top of Mondays find, has taken a staggering amount of drugs off our streets. This is as a direct result of information from the public and really shows the difference people can make by reporting information to us.
