Stuffed Knuts, candles and flowers lay at the entrance of the Zoo to commemorate late polar bear Knut in Berlin on Sunday, March 20, 2011. Hundreds of fans of polar bear Knut flocked to lay flowers Sunday outside his zoo enclosure, mourning the sudden death of a bear who burst into the limelight as a cuddly, fluffy cub hand-fed by his keeper.
The four-year-old polar bear died Saturday afternoon in front of visitors, turning around several times and then dropping to the ground, and falling into the water in his enclosure.
Polar bears usually live 15 to 20 years in the wild, and even longer in captivity, and the zoo is hoping the investigation may help clarify what happened.
Results were expected later Monday or on Tuesday, the zoo said.
In the meantime, people continued to flock to the zoo to sign their name in a condolence book in tribute to Knut.
"Every visit to the Zoo brought happiness, because he was such a warmhearted animal and he brought us all so much fun," visitor Eveline Plat told AP Television News.
