The U.S. city of Memphis on Friday released graphic video footage showing the fatal police assault of a 29-year-old Black man, as cities braced for a night of protests against police brutality.

The newly-released footage from police body cameras shows a group of officers detaining Tyre Nichols, attempting to take him down with the use of a Taser, then giving chase as he evades them.

Subsequent segments – the footage runs about an hour in total, and is audio-only in parts – show Nichols crying out for his mother, and moaning as officers repeatedly kick and punch him.

In one extremely graphic video, officers are seen aiming several kicks at Nichols' face. After pulling him up, they deliver five punches to his face. When he falls to the ground they aim two more kicks at his face.

Five former Memphis police officers were charged on Thursday with murder in the death of Tyre Nichols, who died on January 10, three days after a traffic stop, prosecutors said.

Here’s the timeline of the event

January 7– A traffic stop with fatal consequences

January 7: Tyre Nichols is pulled over by police for an alleged traffic violation after photographing a sunset, according to accounts his family would give later. A confrontation ensues, and he is brutally beaten by five Memphis police officers in an encounter that is recorded by police body cameras.

January 8: Memphis police say in a statement that officers attempted to stop a man for reckless driving on January 7 and he was taken to a hospital in critical condition after two confrontations. The first description of what happened says one confrontation occurred when officers approached the vehicle and the suspect fled on foot. Officers pursued, and another confrontation occurred when they took him into custody, police said. The subject complained of shortness of breath and was taken to a hospital. Due to his condition, police contacted the Shelby County District Attorney General’s Office, which asked the Tennessee Bureau of Investigation to conduct a use-of-force investigation.

January 10 – Nichols' death declared

January 10: The Tennessee Bureau of Investigation says the man involved in the altercation with Memphis officers has "succumbed to his injuries" and identifies him as 29-year-old Tyre D. Nichols, a Black man.

January 14: Family, friends and supporters of Nichols protest in front of a Memphis police station and call for police to release body camera video of the arrest. Nichols’ stepfather, Rodney Wells, tells local media that his stepson suffered cardiac arrest and kidney failure because of a beating by officers.

January 15 – Police provide update on investigation

January  15: Police Chief Cerelyn Davis says she has reviewed information on the encounter and has decided to take immediate action by serving notice of policy violations to the officers involved.

January16: Civil rights attorney Ben Crump announces he is representing Nichols’ family and calls on police to release body camera and surveillance video from the traffic stop. Meanwhile, protesters gather at the Civil Rights Museum to push for the release of police video and call for officers to be charged.

January 18 – Federal investigation declared

January 18: The U.S. Justice Department announces that it has opened a civil rights investigation.

January 20 – Officers involved named and fired

January 20: The five officers involved in the arrest are fired after an internal investigation finds they used excessive force, failed to intervene and failed to render aid. They are identified as Tadarrius Bean, Demetrius Haley, Emmitt Martin III, Desmond Mills Jr. and Justin Smith. All five are Black.

January 23 – Nichols' family views police video

January 23: Nichols' family views the police video with their attorneys, who say it shows Nichols being beaten for three minutes in a "savage" encounter reminiscent of the infamous 1991 police beating of Los Angeles motorist Rodney King. The video shows Nichols was shocked, pepper-sprayed and restrained after he was pulled over minutes from his home while returning from a suburban park where he had taken photos of the sunset. Crump says the family has agreed to investigators’ request to delay making the video public so as not to risk compromising the criminal investigation.

January 24: Shelby County District Attorney Steve Mulroy says the release of police video will be carefully timed to avoid the chance that suspects or witnesses tailor their statements to what they saw in it and asks the public for patience. The timetable rankles activists who had expected the video to be released after Nichols’ family viewed it. Meanwhile, the Memphis Fire Department says two employees involved in the initial care of Nichols the night of his arrest have been removed from duty while the agency conducts an investigation.

January 25: Davis, the police chief, calls the officers' actions "heinous, reckless and inhumane" and makes a plea for people to protest peacefully when the video is made public. She says in a statement issued on social media that other officers are still being investigated for violating department policy and that "a complete and independent review" will be conducted of the department’s specialized units.

January 26 – Officers charged

January 26: The five officers are charged with murder, aggravated assault, aggravated kidnapping, official misconduct and official oppression. Mulroy says they each played different roles in the killing but "they are all responsible." Mulroy also announces that video of the traffic stop will be released to the public the following evening. Nichols' parents say they are satisfied with the charges against the officers. At an evening candlelight vigil, Nichols' mother pleads with supporters to "protest in peace" when the "horrific" video footage is released.

January 27 - Video footage released

January 27: Memphis authorities release video footage showing Nichols being beaten by five officers who repeatedly strike him with their fists, boots and batons as he screams for his mother. The video is filled with violent moments showing the officers, who are also Black, chasing and pummeling Nichols and leaving him on the pavement propped against a squad car as they fist-bump and celebrate their actions. Protesters gather for mostly peaceful demonstrations in multiple cities including Memphis, New York and Washington.
