Student recalls details of attack (3)

"When he was having a seizure, he would always twitch on the ground, foam at the mouth and his lips would turn purple, which was caused by him not having enough oxygen," Zhang told China Daily on Sunday.

Min has a 2-year-old daughter and a 10-year-old daughter. His wife is a migrant worker in the city. The motive of the attack remains unclear.

Most of the students and the woman who were injured received head wounds, and at least seven seriously injured students were transferred to hospitals in Wuhan, Hubei province, and Xinyang, Henan province, on Friday afternoon.

Police took Min to the county hospital, where he was diagnosed as having mental troubles, a doctor told West China City Daily.

Since it released a press statement about the attack on Friday, the local government has remained silent.

China Daily phone calls to the publicity department and the head of the education bureau of the county government went unanswered on Sunday.

This was not the first time violence has broken out at one of the county's schools.

Liu Peng, 17, a student at Guangshan No 2 High School, was killed by a classmate with a knife during a physical education class in October 2011. And Cheng Qian, 18, a student at Guangshan No 1 High School, was stabbed to death in front of the school's gate last month, according to Xinhua.
