Surveillance video shows off-duty CPD officer fighting for gun before shooting alleged robber

CHICAGO (WLS) -- An off-duty female police officer was involved in a shooting Wednesday while attempting to stop a robbery-in-progress, according to Chicago police.

Dramatic surveillance video shows the off-duty Chicago police officer fighting - at one point, even on the ground - to keep her gun out of the hands of a suspect before that gun went off.

The shooting happened around 1 p.m. near 90th and Ada, across from an in-home daycare, in the city's Brainerd neighborhood.

The off-duty officer said she interrupted an apparent robbery in front of an apartment building in the 1300-block of W. 90th Street.

The officer said she produced her firearm and announced she was an officer, police said.

One person was struck by gunfire after a struggle ensued over the officer's weapon, police claim.

A neighbor who shared video of the tussle with ABC7, but asked to hide her identity.

"I could hear her say, 'I told you I'm going to shoot you!' Something to that effect! And when I heard the shots, I was just like, 'Hey! Hit the ground and call the police again,'" the neighbor said.

"It's frightening. It's very scary," another neighbor added.

This surveillance video doesn't capture the moments leading up to or after the confrontation, and it's unclear at what point the shooting happened.

The officer involved was one of their neighbors, according to nearby residents.

"She wasn't, like, scared or anything like that. But, she did hold her own," another neighbor said.

"The tussle that they had almost had me in tears because she's a tiny little person. So, I'm glad that she was able to keep herself together and do what she needed to do to come out alive," a fellow neighbor added.

The person wounded was taken to Christ Hospital in serious condition. The off-duty officer was also taken to a nearby hospital for observation, officials said.

Neighbors who didn't want to go on camera said they didn't hear a shot fired but came outside as police officers began converging on the scene.

As we wait for more details about this shooting, the Civilian Office of Police Accountability is also on scene investigating.

The officer involved will be placed on routine administrative leave duties for 30 days.
