A couple have died after they fell from the high walls of a castle while allegedly having sex.

The bodies of the two men were found naked in the partially dry moat surrounding the Vauban Fort in northern France on Thursday morning.

Their belongings were found on the battlements 40ft above, leading police to believe they were having sex when they fell.

One 31-year-old man was found in the dry part of the moat, while his partner was discovered shortly after in water only 5ft deep.
