CHICAGO (CBS) — An off-duty officer fired shots at a man early Wednesday in the South Chicago neighborhood, after she apparently caught him trying to steal her car. The suspect got away.

Chicago police said the female officer fired shots at an unknown male suspect near 80th and Coles shortly after 4 a.m.

Officers at the scene said the off-duty officer was walking to her car when she saw a man inside. At some point, she fired shots at him.

He was not injured and he ran away. The officer also was not hurt.

Police spent much of the morning processing the scene and searching for the suspect.

One neighbor said the sound of the gunfire woke him up.

“I was on my way to get up, kind of in between sleeping, and then I heard the shots and I rolled over,” Renee Stockton said.

Police said an investigation is ongoing.
