The clashes broke out in Yuhuan County in coastal Zhejiang province, where dizzying manufacturing growth has attracted a torrent of migrant workers from poor parts of the countryside, Reuters reported.
The county government gave a sparse account of the confrontation on a local official Web site (yhnews.zjol.com.cn). But officials left no doubt they were alarmed.
"This was a grave crime of obstructing public security organs in carrying out their duties and assembling a crowd to attack state offices," a deputy head of the Yuhuan police force, Weng Zhengui, told local reporters, according to the Web site.
"We will thoroughly investigate it, sternly attack and show no softness."
Thousands of protests, riots and "mass incidents" occur in China every year, most of them small and never openly reported. But the recent spasm of reported unrest comes at a tense time, with Beijing readying for the Games in August that it has promoted as a show of social progress and harmony.
Rioting broke out in Kanmen town in Yuhuan on the night of July 10 after a migrant worker surnamed Zhang came to a local law-and-order office to complain about injuries from "colliding with a wall" there the previous day, said the account posted late on Sunday. The report did not say how he collided with the wall.
Zhang agreed to be taken to a hospital by police, but on the way an angry crowd surrounded the police and yanked the fuel pipes out of six of their motorcycles.
