NASHVILLE (AP) — Surveillance camera footage released Wednesday of a fatal police shooting in Tennessee appears to show a white police officer chasing a black man and opening fire as he runs away from the officer.

The video was released as Nashville Mayor David Briley announced a "comprehensive review" of policing procedures after last month's shooting.

Nashville Officer Andrew Delke, who is white, fatally shot a 25-year-old black man, Daniel Hambrick, on a sidewalk beside an apartment complex during a traffic stop July 26.

The video from a nearby school seems to show Hambrick fall to the ground after being shot and the officer move slowly closer with his weapon still drawn.

The Tennessee Bureau of Investigation has said police had been looking for stolen vehicles. Bureau spokesman Josh DeVine has said authorities believe that during a traffic stop, Hambrick "reportedly emerged from the vehicle with a firearm in his hand" and the "situation escalated," resulting in Delke firing his gun several times. Hambrick appeared to have a "dark-colored object in his hand" during the chase in a separate video from a housing complex that has also been released, the bureau has said.

A handgun was recovered at the scene, according to the bureau.

On the day of the shooting, Metro Nashville Police tweeted out a photo of a handgun, saying that a fatal police-involved shooting occurred and the "25-year-old man who carried this gun was shot by MNPD officer."

Delke was placed on routine administrative leave while the investigation continues.

Nashville District Attorney General Glenn Funk's office said the footage was released "in an effort to show transparency as much as possible during this investigation," adding that the investigation is expected to be finished within the next two weeks.

The mayor said neither he nor Funk has made any judgments yet on the officer's actions.

"It is absolutely necessary that in this context, we continue to conduct ourselves as a community peacefully and to give the process a chance to reach its final conclusion, while we work hard as a community to improve the way we police in Nashville," Briley said.

The shooting death has heightened calls from community members who want to create a police oversight board in Nashville. A group has gathered more than twice the number of signatures required for a referendum on the topic, and the local election commission needs to approve the language and 8,269 signatures to place it on the ballot.

One of the leading advocates is Sheila Clemmons-Lee, the mother of 31-year-old Jocques Clemmons, who was fatally shot by Metro Nashville Police last year. Funk's office decided not to press charges, saying Clemmons was holding a gun when he was shot.

The mayor said he is for civilian oversight of the police department but said he has questions about that particular proposal.
