Angry crowds have attacked government buildings in south-west China in protest at the death of a teenage girl.
Reports said several thousand people took part in the riots, setting fire to police stations and cars in Wengan county in the province of Guizhou.
Local residents were angered after a police inquiry concluded that the girl, found dead in a river earlier in June, had committed suicide.
Her family accused the son of a local official of raping and killing her.
"About 10,000 people rushed to the site and totally burned down the county party office building, and burned other offices in the county government.
"They also burned about 20 vehicles, including police cars," the official said.
AFP news agency said riots had erupted on Saturday when the girl's uncle was pronounced dead in hospital after seeking justice for his niece.
It quoted locals saying he had been badly beaten - it is not clear by whom.
