A trainer feeds chicken to a tiger during an open training for media at Fuentes Boys Circus in Mexico City June 19, 2014. Circus workers are worried in Mexico City after the capital's local government passed a law prohibiting the use of circus animals, sparking cries from circus performers that the ban will spell ruin for their business. Earlier this month, Mexico City's government overwhelmingly passed a law which imposed stiff penalties of up to $60,000 on circuses in the capital using animals such as lions, camels and horses in their shows. Circuses have one year to comply with the ruling. REUTERS/Bernardo Montoya (MEXICO - Tags: ENTERTAINMENT SOCIETY ANIMALS)

A circus tiger in China mauled and killed on Friday an 8-year-old girl who was visiting the Leheledu Amusement Park in Chongqing town.

The circus was part of their itinerary. The victim, identified as Juan Niu, slipped away from her companions and was unaware that she entered an enclosure of the animal.

The curious girl wanted to see the animal at a closer range, so she went through the bars. Onlookers were aghast at seeing the tiger attack and kill the helpless child.

Although animal trainers managed to pull Juan out of the cage and rushed her to a hospital, it was too late as she was pronounced dead.

The operators of the amusement park, through spokesman Manchu Hung, promise financial compensation for the girl's family as well as to further tighten their security. He said it was the first time that such a horrible incident happened.

But in other parts of China and the world, there had been incidents in the past when circus or zoo animals attack and injure or kill their trainers, caretakers or visitors.

In October, a bear in Henan Province's zoo tore off the arm of a 9-year-old boy after he went past the guard rail and attempted to feed the beast.

In December 2013, a tiger at the Shanghai zoo attacked its trainers who entered the animal's lair to clean it.

In Mexico, a Bengal tiger pounced and killed its trainer in February 2013 by biting 35-year-old Alexander Crispin Suarez on the neck. Before the attack, Suarez was making two large cats to turn in circles while on a big dais.

In the early part of 2014, a Peruvian teacher took her students to a zoo and while attempting to convince her pupils that animals aren't dangerous was attacked by a lion. Although she was tossed like a rag doll by the king of the jungle, the teacher survived the mauling and the painful experience of being proven wrong by the lion itself.
