A fire broke out at a suspected cannabis farm inside an industrial unit on the Tetbury Industrial Estate on Cirencester Road at about 12:45 GMT.[1] Three men were seen running away from the fire, and one of them was detained nearby.[1] Gloucestershire police officers arrested a 26-year-old man on suspicion of drugs manufacture and the production of a class B drug, namely cannabis.[1] The police said the fire had been extinguished, and officers stayed at the scene overnight because extensive damage had made the building unsafe.[1] Officers searched for the two other men with a dog unit and the National Police Air Service, and no one else had been found.[1] Stroud Times reported that the two other men fled across farmland and that no one else had been found.[2] The two men being sought were described as wearing a black hooded top with grey jogging bottoms, and black shorts with a red hooded top.[2]
