Police in Urumqi, capital of the Xinjiang Uygur autonomous region, have detained 253 more suspects in connection with the July 5 riot that left 197 people dead.

Most of the newly-detained were turned in by people from several ethnic groups, police said yesterday.

The latest group of suspects join more than 1,000 who were placed in detention by July 6, the second day of violence in Urumqi. Police did not say how many of that first group have since been released.
