The city on Friday night released body camera and surveillance video of the January 7 traffic stop and beating that led to the 29-year-old’s death in hospital from his injuries three days later.

Protesters in Memphis took to Interstate 55 Friday night after the videos’ release, blocking both lanes of the highway’s bridge connecting the western Tennessee city to Arkansas.

Once pulled to his feet, the video shows officers hitting Nichols in the face multiple times while his hands are restrained behind his body, after which he falls to his knees.

Van Jones, a former special adviser to President Barack Obama, put it this way to CNN after seeing the videos: “(Nichols) goes from a voice from calm (during the initial encounter) to panic … to agony.”

Two minutes after paramedics started attending to Nichols, he is seen falling over to the side and seeming to hit his head hard against a piece of equipment after a bright light was shone in his face.

Police have not been able to find anything to substantiate the probable cause for reckless driving by Nichols before his fatal encounter, Chief Cerelyn “CJ” Davis told CNN’s Don Lemon ahead of the videos’ release.
