A former African-American player with the National Football League (NFL) was brutalized by police in the US state of Georgia during a violent arrest after officers mistook his cellphone with a firearm.

Desmond Marrow, 30, posted a video on Facebook on Thursday, showing what appeared to be three white police officers slamming him to the ground and pinning him down, while he was screaming that he was not resisting.

Marrow said the officers chocked him until he passed out.

“During the arrest the police knocked my teeth out, slammed me on my head and choked me out until I was unconscious,” the black man wrote in the Facebook post.

It is not clear from the clip whether Marrow lost consciousness during the encounter.

Marrow said he also suffered a shoulder strain and a concussion.

“This has affected me mentally and impacted my life in a way I can’t even humanly describe,” the former football player wrote, insisting that he was not crying for sympathy. “I just need it to be known . . . My cry is for JUSTICE.”

Marrow pleaded with social media users to “help me get my voice heard.”

Local media reported that the violent encounter followed an altercation Marrow had with another driver, who had reportedly thrown coffee at Marrow’s car.

A police officer responded to the scene, where a witness said he overheard Marrow threatening to “shoot them.”

Officers asked Marrow whether he was armed and he responded negatively. Police did not find a firearm in his possession.

Police have been under heightened scrutiny in recent years over the use of unnecessary force in encounters with people of color.

Civil rights activists have been protesting under the banner of the Black Lives Matter movement to highlight police brutality against African Americans.
