Ananova:

A Chinese artist provoked a public scare when he hung naked mannequins from the outside of skyscrapers.

Shanghai artist Liu Jin put up four mannequins and put wings on their backs for the work, entitled Wounded Angels.

But passers-by mistook them for real people perilously clinging to the buildings, reports News Morning Post.

One grandmother reportedly required hospital treatment after the shock led to a heart attack.

Police say they received several calls about reports of people hanging from buildings and looking like they were preparing to jump.

"When we got there with the firefighters, we found they were just mannequins," a spokesman said.

Security officers at one building moved the mannequin from the south wall to the north, after neighbours complained.
