SHANGHAI Wildlife Park pledged yesterday to improve security after a young bear was torn to pieces by tigers.

Horrified visitors saw the 3-year-old Asiatic black bear — also called the moon bear — stray into the Siberian tiger zone at the park in the Pudong New Area.

A video clip posted online showed the bear rear up onto its hind legs in a desperate bid to defend itself from four encroaching tigers, before being knocked over and killed.
