According to video recorded by eyewitnesses, the incident took place while the bear was standing on two legs to carry a cart.
Suddenly, however, the animal weighing about 270 kilos turns to the beast tamer and throws him down and begins to hit him with various blows.
The video shows the young children watching the show screaming and looking for the only way out.
According to the Mirror, the bear stopped its attack only when one of the tsikur staff used an electric discharge rod in order to stun it so that the beast tamer could escape.
