The dungeon-like room, discovered by a pair of amateur photographers in an abandoned farmhouse, contained a bed fitted with an elaborate set of harnesses and ropes, the Swedish news agency TT reported Wednesday.
A woman in her 30s told police she had been held captive there after the discovery of the room was made public earlier this year.
Prosecutor Lena Lithner said the woman was abducted from a highway service station in Varberg and was taken to the abandoned farmhouse in southern Sweden.
The room where she was held contained handcuffs, a collection of sex toys and the bed used to hold people against their will.
The suspect, who was not named, said the sex was consensual.
A trial date of June 13th has been set by the court.
