This is the horrifying moment a 200-kilogram black bear mauled a trainer during a circus show in central China's Puyang on October 2.

The shocking video, provided by local media with permission, shows a black bear knocking a trainer named Li Jun to the ground and biting his clothes, while other members of staff use sticks to hit the bear repeatedly to try to get it off Li.

According to reports, a member of the audience allegedly threw a piece of ham onto the stage, but Li picked it up and did not allow the black bear to eat it. The bear then got angry and attacked Li.

Li Jun only suffered scratches to his arm as he said: "The performance animals have no teeth. We have been filing down their teeth since they were young as we are afraid of accidents.”

Li and the bear had have been performing together for several years and only had an incident once.

Li said: "I hope the audiences do not throw any treats when watching the performance because you do not know the animals' temper."

The circus has been suspended, the black bear was sent back to Wuxi City and the trainer Li Jun had vaccination already.

10月2日晚，河南濮阳一马戏团在娄昌湖演出时，突发黑熊咬驯兽师事件。一头约400斤的黑熊突然扑倒驯兽师，死死咬住他的衣服不放，现场多名工作人员采用棒打、推拉等方式，终于将驯兽师解救出来。全程持续2分多钟，场景十分可怕。
据了解，当晚在表演时，一个孩子给黑熊扔了一根火脚肠，黑熊要去吃，驯兽师不让它吃，于是激怒了黑熊。
当地政府回应称，当晚没有观众受伤，该马戏团已停止演出。
10月4日，记者来到事发地濮阳市娄昌湖村，被黑熊抓伤的驯兽师李军站在村口，他的右手手臂上有几处2至5厘米长的伤痕，伤口不深，已经经过处理。李军介绍，他们马戏团参加表演的动物都没有牙齿，加上同事救援及时，虽然视频中的他被黑熊死死咬住，但并没有被咬伤，手臂上的伤痕是被熊爪给抓破的，“这些表演的动物它都没有牙，我们怕发生意外，从小就把它们（表演动物）的牙锯掉了。”
这只攻击李军的黑熊和他算是老相识了，他们合作表演了好几年，从来都没有出过任何事故。李军说，黑熊发怒攻击他的原因，是因为在表演时有观众向舞台上投掷火腿肠，他将火腿肠捡起后没有喂给黑熊吃，黑熊不愿意表演才发生了意外，“希望观众在观看动物表演的时候不要投掷食品，因为你不了解它的脾气。”
娄昌湖村村支书娄彩峰说，他们村是杂技之乡，最近几天正在举办杂技文化艺术节。邀请了全国各地的艺术团来当地进行表演。发生黑熊伤人事件的唐城马戏团来自无锡市。事发后，村委会已经责令其停业整顿，涉事黑熊也已经被送回无锡市，受伤的驯兽师也已经打过疫苗。（视频由河南台提供）
