GU GU the panda has struck again, mauling a tourist who jumped a barrier to retrieve a child's toy, in his third attack on a visitor at Beijing's zoo.
A man from Anhui province went over a 4ft 7in barrier surrounding the panda's outdoor exercise area on Wednesday to retrieve a toy dropped by his five-year-old son, a zoo spokeswoman said.
Gu Gu, who weighs in at 240lb, bit the intruder's legs and refused to let go until zookeepers pried his jaws open with tools.
The Beijing News identified the victim as Zhang Jiao, and quoted tourists as saying Mr Zhang appeared to look around to check if there were pandas nearby before jumping the barrier.
Gu Gu first made news in 2007 when he bit a drunken tourist who jumped into his pen and tried to hug him. The tourist retaliated by biting the bear in the back. In October, Gu Gu bit a teenager who climbed into his exercise area.
The Beijing News said the latest victim suffered damage to major ligaments and is recovering from surgery. Police were investigating the incident.
