Surveillance footage showing a young schoolgirl brutally beating a toddler in a lift in Chongqing has provoked uproar on the mainland. An 18-month-old boy was found by a security guard covered in blood on the ground of a residential compound on the afternoon of November 25. The boy, who had fallen unconscious, was quickly sent to hospital and is now in stable condition, mainland media reported. A surveillance camera in the lift captured images of a schoolgirl, wearing a backpack, entering a lift which had the toddler and his grandmother inside. The grandmother stepped out of the lift and before she realised what was happening, the doors closed with the toddler still inside with the girl, who then picked him up. Footage captured what unexpectedly happened next. In the video, which has been leaked onto social media, the girl, who appeared to be around 11 or 12 years old, suddenly threw the toddler on the ground, and kicked him several times with her foot. She then picked up the toddler again, and then again threw him to the ground, and started to beat him with her fists. The lift then reached the 24th floor, and the doors opened. Footage then showed the girl picking up the toddler and throwing him out of the lift. She then walked out of the lift too. The anxious grandmother followed the elevator to the 24th floor and found the girl, who also lived in the same building on that floor. The girl claimed that the toddler had been taken away by someone else. The grandmother said the girl even offered to help to search for the toddler. It is still unclear how the toddler came down from the 24th floor, but blood was found in the grass of the ground of the compound, about seven metres away from where he was eventually discovered. Police said that the case was still under investigation and refused to give further details. However, many mainland internet users were outraged by the footage which has been widely spread on social media. “I can’t help crying,” a mother wrote on Sina Weibo microblog, “How can a little girl be so twisted as to torture a toddler?” The girl’s father denied to the Beijing News the accusation that the girl threw out the toddler from the 24th floor on purpose, saying that hurting the toddler had been the girl’s way of “expressing her feelings”. However he also admitted that the girl was often scolded and beaten by her parents. “[By beating the boy] she just wanted him to smile to her and to be friendly to her,” the father was quoted as saying.
