 Police carried out a midnight raid on RGHQ Chilmark, an underground bunker constructed in the 1980s in Wiltshire to house and protect government officials and dignitaries in the event of a nuclear attack. 
  
 The site is no longer owned by the Ministry of Defence but the bunker is still intact and the nuclear blast doors are in place. 
  
 Wiltshire Police attended the site after gathering intelligence. 
  
 A spokesman said officers knew the bunker was "almost completely impenetrable" so they waited outside for three people to leave. 
  
 The three men, aged 27, 30 and 45, from Somerset, were detained and officers used their keys to enter the bunker, where they found three more males, aged 15, 19 and 37, all of no fixed address, believed to be working as gardeners. 
  
 They discovered several thousand cannabis plants at various stages of growth. ||||| Image copyright Wiltshire Police Image caption Several thousand cannabis plants with an estimated street value of £1m were seized in a midnight raid on RGHQ Chilmark

The 20-room nuclear bunker was originally intended to protect government officials in case of bombs. Instead, six men were allegedly using it to fill bongs, reports the BBC. During a Wednesday raid on the 1980s bunker known as RGHQ Chilmark in Wiltshire, England, police uncovered a massive marijuana operation with thousands of plants worth at least $1.25 million. "Almost every single room had been converted for the wholesale production of cannabis plants," an officer says of the bunker, per the Telegraph. Six males, aged 15 to 45, were arrested on charges of cannabis production. Three also face human trafficking charges.
