On Monday June 25, and Tuesday June 26, 2012, police and migrant workers clashed in Zhongshan, Guangdong Province. On June 26, nearly ten thousand migrant workers from other provinces surrounded the town government, confronting about one thousand police. The two sides clashed again. Several police cars were smashed and overturned. Many people were injured and sent to the hospital. Armed police blocked all roads.
(According to a government spokeswoman from Shaxi township, a fight broke out between a 15-year-old migrant and a student. Security personnel intervened and severely beat the young migrant, infuriating a group of relatives and other migrants who rioted.)
