LONDON, May 29 (Xinhua) -- A man has been attacked by a tiger Monday according to news reports after a zoo in Britain's Cambridgeshire was evacuated.

Emergency services, including police, paramedics and an air ambulance raced to Hamerton Zoo Park in what Cambridgeshire Police described as a "serious incident".

The zoo park was evacuated just before noon and was then closed for the rest of the day.

Media in Britain reported people running, with scenes of chaos after staff evacuated the public.

The Daily Mirror in London said it understood a man was attacked by a tiger within an enclosure. The report said, however, it was not known if he was a member of staff or a visitor.

Police in Cambridgeshire had earlier issued a public bulletin, saying no animals were loose after rumours spread that a tiger had escaped.

The zoo park opened in June 1990 and covers some 25 acres. It is home to around 500 animals including Malaysian tigers, Bengal tigers, cheetahs, wolves, kangaroos as well as a variety of birds, reptiles and domestic animals.

A full statement is due to be issued later by Cambridgeshire Police.
