The people who have been arrested will face charges in connection with the riot, the Urumqi Public Security Bureau said in a statement.

'They were arrested in Urumqi or in other parts of Xinjiang,' it said.

Days after the violence, the public security departments of Xinjiang and Urumqi issued notices urging people to turn in suspects who were still at large.

'Every suspect, without any exception, will be arrested and punished according to the law to root out any hidden danger,' the statement added.
