     Visitors were still paying 20 yuan to hug Lele and had their photos taken yesterday despite a ban that forbids

any such contact with a wild animal. The ban was introduced more than a week ago.

     "The city zoo broke the law and should be prohibited," said an official at the State Forestry Administration. 

     The administration notice last Monday clearly bans contact with wild or captive animals, the abuse of wild

or captive animals for performance purposes and any improper business related to wild animal products.

     "Close contact with the chimp is the only bit that breaks the ban and we will end that soon," said Beijing Zoo

spokeswoman Ye Minxia yesterday.

     "The chimpanzee performance can't stopped overnight as we have a contract with a company scheduled to

terminate at the end of this year," she said.

     "The zoo is negotiating with the company in the hope of terminating it sooner," Ye said. She refused to

answer directly whether the chimp photo sessions were still ongoing yesterday, instead saying, "It's very likely

that we will cancel it tomorrow."

     Zoo staff confirmed photos were taken yesterday, one employee saying 2-year-old Lele "works" from lo am

t0 3 pm daily, according to "the Legal Mirror".

     Such activities not only damage the mental and physical health of the animals, but also risk the safety of

visitors, according to the official website of the State Forestry Administration where the notice was released.

     "A pet male chimpanzee bit and attacked 55-year-old Chala Nash, causing serious injuries to her face, neck

and hands at her friend's home in Stamford, Connecticut on February 16th last year," CNN reported. "The

friend, Sandra Herold, called "the police, who shot 14-year-old Travis many times after he also attacked an

officer."

     "Putting a blue T-shirt on a wild animal and training it to bare its teeth and parade for visitors might not

enhance that already- troubled image of Chinese animal protection," the State Forestry official warned. "Some

zoos even hit animals and promote themselves with commercials involving animal abuse," he said.

     "Too much focus on the profits too often results in improper treatment of animals, contributing to their early

and unnatural deaths," the notice stated.
