Tigers kill man at Copenhagen Zoo

The man's body was found surrounded by tigers

Tigers at a zoo in Denmark have killed a man after he climbed a fence and crossed a moat to enter their enclosure.

Keepers at Copenhagen Zoo found his body early on Wednesday morning, surrounded by three tigers, a police spokesman said.

The man appeared to be in his early 20s and may have entered the enclosure in order to commit suicide, police said.

He has not been identified but police have said he is not Danish.

A bite on the man's throat was likely to have been the main cause of his death.

The man's nationality was not known and a resident's permit for Denmark was found on his possession, police added.
