A fired Atlanta police officer has been charged with felony murder and another officer faces lesser charges in the shooting dead last week of Rayshard Brooks in the car park of a fast-food restaurant, a Georgia county prosecutor said today.

The death of Mr Brooks - another in a long line of black Americans killed by police - further heightened racial concerns in the United States at a time of national soul-searching over racism and police brutality.

Mr Brooks, a 27-year-old father of three, "never presented himself as a threat", "never displayed any aggressive behaviour" and "did not pose an immediate threat of death or serious physical injury" to the two white officers during the 12 June incident, Fulton County District Attorney Paul Howard told a news conference.

Garrett Rolfe, the officer who shot Brooks and was fired the next day after surveillance video showed his actions, faces 11 charges including felony murder, assault with a deadly weapon and violating his oath of office, Mr Howard said.

Mr Rolfe faces the possibility of life in prison or the death penalty if convicted, Mr Howard added. Felony murder is a charge that can be brought when a person kills someone in the course of committing another felony.

Devin Brosnan, the officer on the scene, was charged with aggravated assault and violations of his oath of office, Mr Howard added. Mr Brosnan, who has been placed on administrative duty, will cooperate with prosecutors, Mr Howard said.

Mr Brooks was running from the officers and was more than 18 feet (5.5 metres) away when Mr Rolfe shot him twice in the back with a 9mm Glock pistol, with one of the rounds penetrating his heart, Mr Howard said.

"I got him," Mr Rolfe exclaimed after the shooting, Mr Howard said, drawing on eight videos of the incident including police body and dashboard cameras, nearby surveillance cameras and witness phone video.

After shooting him, Mr Rolfe kicked Mr Brooks twice when he was laying on the ground wounded and Mr Brosnan admitted to standing on the man's shoulders as Mr Brooks was fighting for his life, Mr Howard said. The officers did not immediately render medical aid, Mr Howard added. The prosecutor recommended that a judge hold Mr Rolfe without bond.

Ongoing protests

The killing of Mr Brooks came amid ongoing protests in US cities prompted by the 25 May death of an African-American man named George Floyd after a white Minneapolis police officer knelt on his neck for nearly nine minutes while detaining him.

That officer, Derek Chauvin, was charged with second-degree murder. Three other Minneapolis police officers were charged with aiding and abetting.

Mr Brooks' family welcomed the Atlanta charges. His widow Tomika Miller told reporters, "I am really hurt, and all I can think about is what if my husband was still here."

Previously released video of the Brooks incident, which escalated from a call about a man who appeared intoxicated in his car at the Wendy's restaurant drive-through lane into a fatal shooting, appeared to show him taking one of the officer's Taser devices and turning and pointing it at Mr Rolfe before being shot.

Atlanta police rules do not allow an officer to fire even a Taser at someone running away, Mr Howard added.

"So he certainly cannot fire a handgun at someone running away," Mr Howard added.

Mr Brooks acted in a calm and "almost jovial" manner and cooperated with the police as the incident unfolded over a period of 41 minutes, Mr Howard said.

Mr Brooks was reported asleep in a car in the Wendy's drive-through lane, blocking traffic. A restaurant employee called the 911 emergency telephone line, complaining about a man who would not move the vehicle and appeared intoxicated.

The killing sparked protests in Atlanta. The Wendy's restaurant was burned down in the unrest.

Atlanta Mayor Keisha Bottoms in the aftermath of the killing announced reforms within the police department. Atlanta's police chief, Erika Shields, resigned following the shooting.
