The China Conservation and Research Center for the Giant Panda in Wolong National Nature Reserve in Sichuan province said on Wednesday it had started rebuilding a fence where a visitor had touched a panda cub.

It was making the fence higher so that visitors cannot reach the pandas and it asked visitors to keep away from the animals. It asked them to refrain from climbing over the fence and from feeding or touching the pandas, said Wang Jisi, an information officer at the center.

On April 7, a woman surnamed Han said in social media that she and somebody else had managed to touch a panda cub without the consent of the center.
