Police have discovered a cannabis farm in Cheltenham, with drugs totalling a street value of around £300,000.
Officers from Gloucestershire Police who specialise in serious and organised crime investigated a property on New Street where they found 208 cannabis plants.
They then found another 152 plants at a house on the same road.
A 44-year-old man has been charged with the production of a class B drug and is due to appear in court next week (13 February).
Gloucestershire Police believe the farm was run by an organised crime group.
In just one week the police discovered five other cannabis plants in the county, resulting in more than £750,000 of the drug being removed from the streets.
Officers say the factories generate money which goes into sexual exploitation, human trafficking and the purchase of firearms. It also goes into the purchase of class A drugs such as cocaine.
