More than 15,000 cannabis plants with a street value of £4million were found at an industrial unit in North Lincolnshire. The operation was so big that four former Tesco home delivery vans were used to distribute drugs to cannabis dealers across Scunthorpe, Grimsby, Doncaster and large parts of Lincolnshire and from the factory in Scunthorpe. Five Vietnamese men, who are the suspected growers, were found inside. It is believed they were illegally trafficked to look after the farm. Three of the men were caught. Another two fled the scene and are being hunted by police. The estate where the farm was found was being used by a mixture of major distribution and manufacturing companies and small car repair and business units.
