The Budokan gymnasium in Frimley was closed amid claims that it was at the centre of a massive drugs ring.
More than £2million worth of ecstasy, cocaine and canna-bis was seized and 22 people arrested in raids on 37 addresses across Surrey, Hampshire, the Thames Valley and London.
Supt Mike Day said the Budokan gym was used by a number of those arrested. It remained sealed off as this newspaper went to press.
Around 200,000 ecstasy tablets, worth an estimated £2million, were seized from one address in Byfleet.
Supt Day said the seizures were a major success in the crackdown on the supply of Class A drugs. A significant amount of the drug market had been removed.
The arrests were the result of police intelligence exercise, dubbed Operation Sculpture, that centred on the Budokan gym.
A suspected cannabis factory and an ecstasy ‘pill-press’ were also seized from an Ash address, along with a loaded sawn-off shotgun, gas gun and a stun gun, known as a Tazer.
Police also found 125kg of cannabis resin with a street value of £100,000, 3kg of cocaine valued at £60,000 and 15 large bags of ‘skunk’ cannabis, worth £30,000 at the premises in Ash.
Tens of thousands of pounds in cash was also discovered there.
Two handguns and ammunition were found in the raids and nine high-performance vehicles, including a Porsche, BMW and Lexus, believed to have been stolen from the Surrey Heath area, were impounded.
On Friday, six people, including a policeman, appeared before Woking magistrates.
Pc Kevin Davies, 28, of Rye Close, Farnborough, based at Guildford police station, is charged with conspiracy to pervert the course of justice and conspiracy to supply cocaine and ecstasy.
He was remanded in custody until Monday.
Surrey police civilian emp-loyee Emma Barnett, 29, of Queens Court, Alexandra Road, Farnborough, is charged with conspiracy to pervert the course of justice and conspiracy to supply cocaine and ecstasy.
Piers Ravenhill, 30, Ash Hill Road, Ash, and Ben Rickwood, 27, Scotland Farm Road, Ash Vale, are charged with conspiracy to supply cocaine and ecstasy and conspiracy to pervert the course of justice and handling charges.
All four were remanded in custody until Monday.
Sixteen people have been released on police bail, pending further inquiries.
One innocent police officer was given a rude awakening by colleagues who were part of the dawn raid teams.
An Aldershot flat belonging to a Guildford-based Pc was stormed by around ten officers at 5.30am on Thursday.
Confirming the mix-up, Supt Day explained: “One of the addresses visited is now owned by a police officer.
“There was no arrest at that premises and he is not connected in any way with the operation.” Any damage caused to the officer’s property would be paid for by the police, Supt Day said.
