NEW YORK (AP) – Authorities say a patron at the Bronx Zoo leaped from an elevated monorail train and plummeted into an exhibit, where he was mauled by a tiger.

New York City police say the man lost a leg in the attack.

Zoo director Jim Breheny says the mauling happened Friday afternoon in the Wild Asia exhibit, where a train takes visitors past elephants and deer and over a tiger enclosure. He says the man leaped from the train and cleared a perimeter fence.

Workers used a fire extinguisher to back the tiger off. The man then rolled under a wire to safety.

Police said the 25-year-old man has been hospitalized in critical condition.
