Los Angeles area police have launched a huge manhunt for a sacked officer who is suspected of killing three people, including a former colleague.

Christopher Dorner, 33, is alleged to have gunned down a policeman and wounded two others on Thursday morning.

Protection teams are guarding 40 individuals who are believed to be targets.

He is also wanted over the shooting deaths of a couple at the weekend.
