Officers from North Yorkshire Police discovered a large-scale cannabis grow at a disused barn on farmland in the village of Hunton, between Leyburn and Bedale on Wednesday 21 October.
Members of the local community reported suspicious activity at the barn with a number of vehicles and people coming and going to the location.
Upon arrival to the barn, police found well-organised hydroponics system, electricity meters bypassed and a quantity of cannabis plants in the early stages of cultivation.
"Often those involved in the actual cultivation and set up on the ground can be vulnerable and may be exploited by organised crime groups so putting a stop to these types of operations has a far wider reaching impact than simply stopping drugs from becoming available in our communities.
"Everyone can play their part by remaining vigilant and reporting any suspicious behaviour to the police so that we can take action."
