KEY POINTS:
Berlin Zoo has denied allegations that its baby polar bear Knut is responsible for the sudden demise of one of its older attractions, a 22-year-old panda who was found dead in her cage.
Just four days after the euphoria over the debut of three-and-a-half-month-old "Cuddly Knut", the mysterious death of Chinese-born Yan Yan stole the headlines in German newspapers this week.
But the zoo denied claims the commotion caused by Knut could have stressed the black and white bear, who spent much of her time chomping at bamboo shoots.
