A 29-year-old man drowned a bizarre accident after getting stuck upside down in a drain trying to fish out his dropped headphones and jewellery.

The victim, not been named by police in Braunschweig, central Germany, had slipped and become wedged halfway down the drain with his head covered by water on 3rd May.

An astonished passing bus driver spotted his legs sticking out of the drain and called police.

Police officers pulled the man from the drain and performed CPR before rushing him to hospital where he was declared dead a few hours later.

After pumping out the water, firefighters recovered a ring and headphones, which were confirmed as the man’s belongings.

A police spokesperson said: "The ring was subsequently identified as belonging to the man, who was a Gifhorn resident."

Clothes found near the gully showed he had partially stripped before attempting to fish out his possessions.

Police have ruled out foul play and have listed the death as an accident.
