A black teenage robbery suspect was fatally shot in the back while fleeing two white Colorado police officers, new surveillance video shows.

De’Von Bailey, 19, was running from the scene of a reported robbery in Colorado Springs about 6:45 p.m. Saturday when he was shot by pursuing officers before falling to the ground and being handcuffed by one of the cops, according to the report in The Gazette.

A third officer arrived, dropped an unknown object on the ground and appeared to perform CPR on Bailey, who was later pronounced dead at a local hospital, the report said.

The video is from a surveillance camera at an apartment complex. Police said the officers wore body cameras, but that video has not been released.

The officers were dispatched to a report of a robbery on East Fountain Boulevard when police said they encountered Bailey and another man — one of whom reached for a weapon, police said.

It is not clear from the video if Bailey had a weapon.

The incident is being investigated by the El Paso County Sheriff’s Office, which is standard practice in police-related shootings.

The shooting sparked a protest at Colorado Springs City Hall this week, prompting Mayor John Suthers to call for patience on Tuesday while the probe moves forward.

“We know that there can be frustration with the time this takes, but we cannot compromise the investigation by failing to spend the appropriate time gathering facts,” Newsweek quoted the mayor as saying in a report Wednesday.
