Leicestershire Police say the discovery of a Cannabis farm on a disused airfield in Melton Mowbray is one of their largest ever hauls.
Two thousand plants were being cultivated in a derelict factory and lorry container, with an estimated value of two hundred and fifty thousand pounds.
Police were tipped off by members of the public reporting suspicious activity. They believe a second criminal gang were spotted trying to steal the plants.
When they arrived at the site, they were able to follow a Hansel and Gretal type trail of cannabis leaves and debris, which led the directly to the factory containers.
Three men have been arrested.
