The couple called the police after their sex game had left them in a tricky situation as their keys failed to open their handcuffs and they were left locked to each each other.
Police needed the help of bolt-cutters to prize the pair apart.
“They had hoped that their keys would fit, but we had to use a type of bolt-cutter,” said Christian Wehlin for Östergötland police.
There was another man in the apartment when the police arrived. He had been trying to help the couple out of their bind but had been unable to force the handcuffs open.
