From Guizhou Metro Daily, translated by CDT:
Hundreds of people smashed police cars in Guiyang at midnight of July 10, after para-policemen beat up a newly arrived migrant worker Mr. Guo, who refused to pay for a temporary residency book. The incident happened around 9pm July 10 near a bath house at Luchongguan Road in Guiyang.
The mob attacked arriving police who came to send the injured migrant worker to the hospital. Police cars were smashed and flipped. When reporters drove toward the police station for an interview, the car was stopped and smashed too. The reporters spared a beating only after identifying themselves as “reporters” and someone among the crowd said no violence on the reporters. But a taxi driver and his car were beaten up and many cabs nearby drove to escape.
Only when armed police came in dozens that the mob disbanded, about 3am. The police bureau is investigating the incident, including the para-policemen who beat the migrant worker. [Full Text in Chinese]
