An elaborate birthday surprise in Bielefeld, Germany led to an emergency police operation after a concerned member of the public called them.
Police rushed to rescue a man in a park with his head buried in a pile of sand, only to find a life-sized shop mannequin.
The kneeling dummy dressed in jeans and a shirt had a sign beside it saying, '50 na und?', (50 and what?).
"It was clearly a prank intended for someone's 50th birthday," said a police spokesman. "But the person who called us was clearly convinced by it and called us in good faith thinking they were helping someone in trouble," they added.
