Newly released surveillance footage shows the moment a black man is shot dead last month in Tennessee by a white police officer as he runs away on a leafy street.

In the footage released Wednesday by the Nashville District Attorney’s Office, Officer Andrew Delke can be seen opening fire on 25-year-old Daniel Hambrick on a sidewalk near an apartment complex during a traffic stop July 26.

The video shows Delke shoot Hambrick from a distance before the officer — with his gun still drawn — moves closer to Hambrick as he’s down on the ground.

Police have said Hambrick was armed at the time — and a day after the shooting, the Metro Nashville Police Department tweeted out a photo of the gun that Hambrick allegedly was carrying.

The video, however, does not appear to show Hambrick turn around toward the officer as he runs away.

“I just want justice for my son,” Hambrick’s mother, Vickie Hambrick, said during an emotional news conference Wednesday with the Nashville NAACP. “That’s all I’m asking. And for all the young black guys and young women, I want justice for them. I love them all.”

Hambrick’s uncle, Sam Hambrick Jr., questioned how his nephew could have been a threat if he was running away.

“I don’t care if I have a hand grenade in my pocket; if I’m running away, I can’t be a threat to you,” Hambrick Jr. said.

The release of the video has prompted the Nashville NAACP to call for Delke to be fired and charged with murder. The group also called for the FBI to open a civil rights probe and a review of the Nashville Police Department.

At a separate news conference, Nashville Fraternal Order of Police president James Smallwood said the “grainy video” that was released “in no way paints a complete image of what occurred that day,” according to the Tennessean.

He also criticized the district attorney’s office for releasing the video while the investigation into the shooting plays out.

“To be clear, we would prefer that the entire investigation of this case would have been released in its entirely, rather than piecemeal one at a time,” Smallwood said.

Smallwood also argued that Hambrick could have fired over his shoulder or under his arm.

“It is our firm belief that Officer Delke acted reasonably under the totality of the circumstances,” Smallwood said, according to local reports.

Hambrick family attorney Joy Kimbrough said the officer shot the man “in the back of the head.”

“Daniel runs, which is still not illegal — you can run,” Kimbrough said. “He’s running. The police officer chases him. The police officer chases him with his gun drawn. He chases him and at some point he slows down and executes him. He shoots him repeatedly from behind. He shoots him in the back of his head.”
