South Yorkshire Police’s Burngreave neighbourhood policing team found a cannabis factory at a property on Sturton Road, Burngreave in May this year. Officers said in a statement: “As the front door travelled at speed, so did the sole occupant of the address, running through a room full of cannabis plants like a scene out of 'Lock Stock and Two Smoking Barrels’ in an attempt to escape.” A man was arrested for class B drug cultivation as well as immigration offences. A search revealed around 50 mature cannabis plants in four rooms. Photo: Google
