Germany’s celebrity polar bear cub Knut has received an anonymous death threat, causing alarm at Berlin Zoo on Thursday and prompting heightened security. The zoo has trebled the number of minders to 15 responsible for the safety of media star Knut, who has been on newspaper front pages and news shows across Germany and around the world for weeks.

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.” Source
