Bullied student uses rat poison for revenge

A student who was bullied at school sought revenge by poisoning 10 classmates in Kunming, capital of Yunnan province.

On Monday afternoon, a 12-year-old student surnamed Liu from the Yanglin town No 1 Middle School, put rat poison into the thermos bottle in his classmates' dormitory.

Liu wanted revenge because he was often bullied by his classmates, and he thought "the rat poison would give the bullies diarrhea", a Kunming police investigation found yesterday.
