(CNN) — Twenty-two primary school children have been wounded in a knife attack in central China, the state-run news agency Xinhua reported Friday.
The attack took place Friday morning at the entrance to the Chenpeng Village Primary School in Henan province, Xinhua said, citing local authorities.
A local resident was also wounded in the attack, it said.
Police say they have detained a suspect, a 36-year-old village resident, the agency reported.
China was hit by a spate of knife and cleaver attacks on school children in 2010, some of them fatal.
A number of measures were introduced at the time, including increased security at schools across the country and a regulation requiring people to register with their national ID cards when buying large knives.
