Watch moment Dorset Police cut through door of cannabis farm
Thousands of factory-farmed cannabis plants have been seized by police in Dorset.
The 12 raids were part of Operation Mille, a country-wide co-ordinated drugs enforcement operation against organised crime groups.
About 1,000 search warrants have been executed by police nationally since 1 March.
Dorset Police said the raids showed that gangs were "exploiting vulnerable people" and "making huge profits".
