A man was found dead in a tent and a woman airlifted to hospital yesterday after attending an outdoor sex festival.

The man, who was in his 50’s, and the woman were understood to have been at the two-day Flamefest, a so-called “kinky rave”, in woodland near Royal Tunbridge Wells in Kent.

Detectives and paramedics were called to a campsite shortly after 6am when the two people were discovered unconscious.

Attempts to revive the man were unsuccessful, and his death was last night being treated as “unexplained” while investigations continue. The unconscious woman was taken to hospital by air ambulance where she was being treated.

It remained unclear what caused the pair to lose consciousness. One man, who spoke on condition of anonymity, said barbeque apparatus had been removed from a tent, raising the possibility they were overcome by fumes. Others claimed the man’s death may have been drug-related.
