A man stabbed eight school children to death and injured five others while they were waiting at their school's gate in Nanping City, Fujian Province, on the morning of March 23.

Police arrested 42-year-old suspect Zheng Mingsheng, a former community doctor in Nanping. Zheng is a native of Nanping and used to work at the Mazhan community clinic before resigning in June 2009.

The local prosecutor said on March 24, Zheng, who showed no sign of any mental illness in conversations, told investigators that he developed hatred toward society after failing to find a job and breaking up with his girlfriend.
