Los Angeles, Aug 10 (DPA) More than 250 inmates were injured and 55 brought to hospital following a riot at a men's prison in California that was brought under control Sunday, media reports said.

The riot broke out between black and hispanic inmates at the Chino prison outside Los Angeles late Saturday and took more than 10 hours to bring under control, the Los Angeles Times reported. The facility remained in lockdown Sunday, prison spokesman Mark Hargrove was quoted as saying.

Officials cleared the barracks after about 1,300 inmates began rioting and at least one building was damaged by fire.

Eighty officers responded to the riot and used tear gas and rubber bullets to bring the situation under control.
