You Knuts!

Good Lord, as if this bear isn't having a hard enough time!

Germany's celebrity polar bear cub Knut has received an anonymous death threat, causing alarm at Berlin Zoo Thursday and prompting heightened security.

"We were contacted by the zoo about a (threatening) letter it had received," said a police spokeswoman, adding officers had investigated but they did not believe it was serious.

Top-selling Bild newspaper said the zoo had received a hand-written fax from a suspected animal hater with the words: "Knut is dead! Thursday midday."

The poor lad was rejected at birth by his mother, then his twin brother died. Soon after that there were animal rights activists who were saying that he should be killed because he was being brought up by humans and would thus never be a "real" polar bear.

Now this, direct death threats.
