A 35yo man has injured eight children at a Chinese primary school after going on a meat cleaver rampage.

SHOCKING footage has emerged of a crazed man attacking children with a meat cleaver in a drug-fuelled frenzy at a Chinese primary school.

One student is in a coma and seven others injured after 35-year-old Chen Zuihang allegedly went on a bloody rampage through the school in Macheng on Tuesday.

Chilling CCTV video showed the attacker swiping wildly at running children and walking around the playground with blood smeared on his shirt.

The first and second grade students were on their lunch break during the frenzied 60-second attack.

“It seems he slashed at them rather than chopping hard, which would have killed most of them instantly,” a police spokesman said, according to The Mirror.

“The scenes of panic at the school were indescribable. These youngsters had no idea what was going on.”

Teachers tackled the assailant with a garden hoe before he was arrested.

The Independent reported the alleged attacker man was able to sneak inside the school grounds in a delivery truck, holding the meat cleaver behind his back.

The students were rushed to Macheng City People’s Hospital for treatment.

South China Morning Post reported one child has been discharged, while two others had surgery and are in a stable condition.

Authorities said the suspect Chen Zuihang was a migrant worker who tested positive for methamphetamine in a urine drug test following his arrest.

Police said he had a history of drug use, and was detained by his hometown police in Luoyuan County of east China’s Fujian Province for drug use in 2006 and 2011.

The school head was suspended and school security chief was sacked, according to China.org.cn.
