A young postman who killed a robber in a car chase was deemed a "good Samaritan" by police in Shaoguan, Guangdong province, on Monday.

Police said the postman, in his early 20s, was parking his van when he saw two men on a motorcycle grab a woman's purse and take off. Without hesitation, the postman drove his van after the two robbers.

The robbers didn't stop at the postman's warnings and the motorcycle suddenly slipped and hit the van at a construction site about 500 meters from the robbery.
