Gu Gu the panda has struck again, biting a third visitor at the Beijing zoo. A Chinese tourist went over a 4-foot barrier surrounding the panda's outdoor exercise area yesterday to get a toy dropped by his son; the 240-pound Gu Gu bit his legs and refused to let go until zookeepers pried his jaws open with tools.
Gu Gu first made news in 2007 when he bit a drunken tourist who jumped into his pen and tried to hug him. In October, Gu Gu viciously bit a teenager who climbed into his exercise area out of curiosity. The latest victim suffered damage to major ligaments and is recovering from surgery. Zoo officials are considering unspecified measures to prevent further incidents.
