Fishermen's find sends mum 50 shades of red

Police investigating a suspected crime scene in Sweden were shocked to learn it was a woman's secret sex chamber.

Two fishermen contacted the authorities after finding the 'dungeon' in an abandoned military bunker near the town of Nordmaling.

It featured a bed, ropes, leather restraints and adult toys, reports Sweden's Aftenbladet newspaper.

But when news of the hide-out became public, a single mum called Lena came clean about the bunker.

Lena, who is in her 40s, admitted equipping the room for trysts with a man she had recently met but said she had learnt her lesson.

"I just wanted to test my limits," she said. "Sweden is not really such a free country when it comes to sexuality."
