Hundreds of people have rioted in southwest China's Yunnan province, overturning and smashing several police vehicles.

Local media reports say the riot broke out in Guiyang city, shortly after a man was allegedly beaten by officers hired by police for not possessing a temporary residence permit.

The AFP newsagency says about 300 people, mostly farmers turned migrant laborers, took part in the riot after being outraged by the beating.

Police sent to handle the riot were chased by rock-throwing protesters and nine police vehicles were damaged including several which were overturned by the crowd.

Local police have confirmed the incident and say one police officer is receiving medical treatment.

Police have arrested about 10 people.
