BERLIN – Berlin's beloved polar bear Knut, who rose to international stardom as a cuddly cub hand-raised by zookeepers, died suddenly on Saturday, a zoo official said.
The world-famous bear died alone in his compound without warning, bear keeper Heiner Kloes told The Associated Press.
"It was a completely normal day: He was with the female bears before, who had just been shut away," Kloes said. "Then, Knut strolled around the enclosure, went into the water, had a short spasm and died."
A post mortem will be conducted on Monday to try to pinpoint the cause of death, he said.
