A large-scale cannabis factory has been discovered by police on the site of a underground former nuclear bunker.
According to Wiltshire Police, several thousand cannabis plants with a street value of £1m were seized in the raid on RGHQ Chilmark yesterday.
Six men have been arrested on suspicion of cannabis production at the extensive facility – which boasted almost 20 rooms, with each being used for the cultivation of the Class B drug on an industrial scale.
The former Ministry of Defence bunker was previously used in the 1980s to protect local government officials and dignitaries in the event of a nuclear attack.
Police were forced to wait until the suspects left the bunker, described as ‘completely inpenetrable’, before they carried out the raid.
Detective Inspector Paul Franklin described the factory as an ‘enormous set-up.’
He said: ‘There are approximately 20 rooms in the building, split over two floors, each 200ft long and 70 ft wide.
‘Almost every single room had been converted for the wholesale production of cannabis plants, and there was a large amount of evidence of previous crops. This was an enormous set-up.
‘It is almost impossible to work out how many plants are inside, but we are talking thousands rather than hundreds and we would estimate the value of the crop at over £1 million.’
Three men, aged 15, 19, and 37, of no fixed address, have been arrested on suspicion of cannabis production.
A further three men, who are aged 27, 30 and 45, all from Somerset, were subsequently arrested on suspicion of cannabis production, alongside human trafficking offences.
