A baby boy was killed after a school girl found him alone in a lift and then allegedly thew him off a balcony.

Yuanyuan, who is thought to be just under two years old, was in a lift with his mother in Chongqing, southwest China.

CCTV footage in the lift shows as his mother was wheeling out his small green bike from the lift the doors abruptly shut.

Seconds before the 10-year-old girl entered the lift and picked up Yuanyuan as the door started to close as his frantic mother sets the bike down.

The grainy black and white footage shows the schoolgirl, who is wearing a backpack, holding the child for a few seconds before slamming him into the ground.

As he struggles to get back up she repeatedly kicks him, hits him and stamps on him.

When the lift doors open on the 25th floor she is seen grabbing Yuanyuan off the metal floor and pushing him out.

Shanghaiist, an English language Chinese news website, reports that is when the girl threw the child off the building from either a window or a balcony.
