A Han Chinese crowd confront riot police after they arrested two Han men who were part of a mob that chased down a Uighur in Urumqi. They caught up with the Uighur and beat him before the police intervened firing shots in the air and arresting the two Han attackers. The mob then attacked the police to try and stop the arrests. Ethnic violence between the Uighur and Han people had erupted in the city a few days earlier.
