A knife-wielding man slashed 22 children and an adult at an elementary school in central China on Friday, state media reported, the latest in a series of attacks on schoolchildren in the country.
The man attacked the children at the gate of a school in Chenpeng village in Henan province, the Xinhua news agency reported.
Police arrested a 36-year-old man, identified as villager Min Yingjun, Xinhua said. It did not give further details of the extent of the injuries.
There have been a series of attacks on schools and schoolchildren around China in recent years, some by people who have lost their jobs or felt left out of the country's economic boom.
The rash of violence has prompted public calls for more measures to protect the young in a country where many couples only have one child.
In 2010, a man slashed 28 children, two teachers and a security guard in a kindergarten in eastern China.
