ANSHUN, Guizhou - The family of a street vendor who is suspected to have been beaten to death by city management officers in a Southwest China city has allowed police to do an autopsy after a protest ended on Wednesday morning.

Hundreds of protesters gathered on Zhonghuanan Street in the downtown of Anshun city, Guizhou province, on Tuesday afternoon, accusing city management staff of beating the vendor.

Police said about 30 protestors and 10 policemen suffered injuries in the protest.

The vendor has been identified as Deng Qiguo, a 52-year-old man with a disability. He died at around 1:47 pm Tuesday after having a dispute with city management staff, according to a government spokesman.
