New video has been released by local police showing the school knife attack that hurt 23 youngsters and an adult in Central China's Henan Province.
The knifeman attacked the victims at the gates of their school on Friday, the same day as the massacre at Sandy Hook elementary school in the United States.
As the wounded were being treated in various hospitals, local police released the surveillance video which captured parts of the incident.
The footage showed a male suspect wearing blue jacket and white trousers chasing after a girl. He was seen waving the knife in his hand in front of the school.
The suspect, Min Yongjun, was arrested at the scene on charges of jeopardising public security.
State television said police were still trying to uncover the motive for the attack.
