CCTV footage apparently showing police beating the man
Footage of a homeless man being beaten and tasered by police just five days before he died has been shown in a court in California, reports Sky News.
Kelly Thomas, 37, died on July 10, 2011, after the incident outside a bus station in Orange County.
Officer Manuel Ramos, 38, has been charged with second-degree murder and involuntary manslaughter and faces a maximum of 15 years to life in prison if found guilty.
Corporal Jay Cicinelli, 40, has been charged with involuntary manslaughter and use of excessive force. He faces up to four years in prison if convicted.
Both have pleaded not guilty to charges over his death, which sparked protests by local residents and an FBI investigation.
The video was shown during a preliminary hearing in which a judge is set to decide if there is sufficient evidence for the two policemen to stand trial.
The grainy footage from the bus station camera, combined with audio picked up on radio microphones the officers wore, has never been played in public before the hearing on Monday.
Defence lawyers claim there is not enough proof to say the officers were directly responsible for Thomas' death and that medics could have been to blame.
