"Police in northwest China's Xinjiang Uygur Autonomous Region on Sunday captured the only rioter at large after a violent terrorist attack," state-run Xinhua news agency said.
The captured man is identified as Yiblayan Eli, a member of the 17-member gang behind the attack in Lukqun Township in Shanshan County in the region's Turpan Prefecture, a Xinjiang police statement said.
Fearing their plot might be revealed after one gangster was arrested on Tuesday, 16 rioters attacked the township's police stations, a local government building, a construction site, a private store and a hair salon on Wednesday and set police cars afire, the report said.
A number of people including two police officers, were killed by the knife-wielding rioters.
Among the victims, 16 were from the Uygur ethnic group. Twenty-one police officers and civilians were also injured in the attack.
The police shot and killed 11 rioters and captured another four who were injured at the scene, while one managed to escape.
Meanwhile, reports say China poured security forces beefing security in the region to prevent riots from spreading.
