I filmed the video myself. It was filmed at the Bifengxia Giant Panda Base I filmed it in about November 2010.

My daughter and I were doing a sight-seeing tour of China, we went around the reserve and saw a group of wealthy Chinese tourists that had paid for the privilege of feeding the Giant Pandas. We noticed that the panda in the cage in the video appeared particularly aggressive and unsettled. One of the Chinese tourists, the woman in the video, fed it one of the cake treats. The panda seized hold of her hand in its jaws (its jaws are strong enough to crush bamboo), the panda was tearing at her hand so strongly we feared that her arm would be pulled from its socket. The actual event lasted longer than the video, a male keeper was vomiting during the attack with the shock of what was taking place.

The keepers were pulling at the woman, trying to free her from its jaws, the panda had placed its paws against the bars to apply greater leverage in its efforts to tear the treat from the woman's hand. I expected at any moment that the arm would be pulled from the woman's body. The panda bit off a finger so that it and the people fell to the ground. The woman had been seriously injured. The injuries to her arm would have been severe and her arm could never fully recover from what happened. The psychological shock would also have been tremendous. I feel sorry for her to this day. My daughter (aged about 20 at the time) also vomited as she was watching the attack. As the video shows it was truly horrible.
China is a totalitarian country, there are military guards everywhere. I knew that the keepers would alert the guards to the fact that I had filmed the attack so I was in a hurry to leave the reserve rapidly before they confiscated my film (and probably my equipment). Pandas are held out to be such gentle passive creatures, we know that they are no different to any other large, bear-like animals. They are actually very dangerous. I am sure that the Chinese, that have invested multi-millions into their breeding programs and benefit from the tourist influx, would pay a fortune for this video.
