The moment a woman was mauled by a polar bear after she jumped into its enclosure at Berlin Zoo was caught on camera.
The intruder was attacked just yards away from Knut, the abandoned bear who became famous around the world.
Zookeepers managed to push the bear away and carry the woman from the cage.
The mauling took place inside an enclosure occupied by four polar bears not far from Knut's home.
Heiner Kloes, a Berlin Zoospokesman, said the enclosure is surrounded by a fence, a line of hedges and a wall.
The woman was taken to a hospital for treatment.
Police did not say why she jumped in with the bears.
"The woman has proved herself to be careless by jumping into the enclosure," a police spokesperson said.
"Logic tells us that polar bears will do this type of thing in this situation."
Last December, a man who later described himself as "lonely" jumped into the cage of the zoo's most famous polar bear.
But he emerged unscathed after zookeepers managed to distract Knut with beef.
