ZHENGZHOU - A knife-wielding man attacked eight people aboard a train in central China's Henan province early Sunday, killing one and injuring seven others before police detained him.
The attack occurred at 00:20 a.m. Sunday on train No. K862 travelling from Lanzhou, capital of northwest China's Gansu province, to Wuhan, the provincial capital of Hubei province, said a spokesman from Henan's Zhengzhou Railway Bureau.
The injured were taken to three hospitals in Henan's Luoyang city. Their injuries are not life-threatening.
A preliminary investigation revealed the suspect is a psychopath, and a sudden onset of lunacy may have caused the tragedy, police said.
Police are investigating how the knife passed through the security check at the railway station.
