A large cannabis factory has been discovered by police in a former nuclear bunker.
Thousands of cannabis plants with an estimated value of £1 million were seized in a midnight raid on Wednesday (February 22), the BBC said.
Wiltshire police arrested three men on suspicion of cannabis production and another three on suspicion of cannabis production and human trafficking offences.
Almost every room in the building had been converted into a cannabis plant, police said, which was built in the 1980s to protect local dignitaries and government officials in any nuclear attacks.
Detective Inspector Paul Franklin said: "There are approximately 20 rooms in the building, split over two floors, each 200ft long and 70ft wide."
He also said that he believes it is "one of the largest crops ever discovered" in the county.
The bunker was described as "almost completely impenetrable," as police had to wait for suspects to leave before they could get inside.
