Twenty-two children and one adult have been injured in a knife attack outside a primary school in central China, according to police.
A police officer said the attack in the Henan province village of Chengping happened shortly before 8am on Friday as students were arriving for classes.
The officer said a 36-year-old villager, Min Yingjun, was in police custody. She declined to give her name, as is customary among Chinese civil servants.
A county hospital administrator said the man first attacked an elderly woman then students, before being subdued by security guards. Guards have been posted in schools across China following a spate of attacks in recent years.
He said two students had been transferred to better-equipped hospitals outside the county.
