Washington, June 6
A female police officer in Los Angeles has been convicted for threatening a handcuffed woman, striking at her throat with an open hand and kicking her in the crotch, media reported.

The video of the incident, recorded by a patrol car camera, persuaded jurors to convict Mary Oâ€™Callaghan, 50, on Friday, the Los Angeles times reported.

Oâ€™Callaghan faces three years in state prison for assaulting Alecia Thomas in the back of a patrol vehicle in July 2012.

Thomas, 35, lost consciousness and soon after died at hospital. Oâ€™Callaghan was not charged in connection with the death.

The prosecution\'s case centred on the video, which showed O\'Callaghan jab at Thomasâ€™s throat with an open hand and threaten to break her arms and kick her in the crotch. In the video, Oâ€™Callaghan then raises her boot and strikes Thomas.

A video from a dashboard camera in another patrol car, which was also played during the trial, recorded Oâ€™Callaghan laughing and smoking a cigarette as she peeked inside the car at Thomas, whose legs were tied with a nylon hobble restraint.
