KUNMING -- A prison in Southwest China's Yunnan province offered a reward of 100,000 yuan on Wednesday for information leading to the arrest of an escaped convict.

A class-A warrant has been issued for Zhang Lincang, 27, who escaped from No. 1 Prison in Yunnan Tuesday morning.

Zhang was sentenced to life imprisonment for drug-trafficking, and started his sentence in January 2017.

"Zhang left the site where inmates were working at around 8:20 a.m. Tuesday, stole a truck and fled," the report said. He abandoned the truck on a road 2 kilometers from the prison.
