A 32-year-old German woman was seriously injured in a polar bear attack at the Berlin zoo which is also the home of the famous polar bear Knut, Berlin police reported. 

The victim, a resident of Brandenburg near Berlin, for still unknown reasons, jumped in the moat that divided the bears from the visitors of the zoo when the bears were just being fed, police said.

A bear then jumped into the water and bit her, inflicting grave injuries to the woman.

The Berlin zoo became popular in 2007 when a baby polar bear, Knut, was born there and was soon after rejected by its mother. It lived thanks to the care of zoo keepers who bottle-fed him. The photographs of the cute bear travelled the world.
