CHICAGO (CBS) — Chicago police shot and killed a 41-year-old man Monday morning in the Belmont Central neighborhood, after an off-duty officer saw a man and woman running down the street in handcuffs, and told the officer they had been kidnapped.

Chicago Police Sgt. Cindy Guerra said, around 6:45 a.m., an off-duty officer saw a man and woman running down the street, handcuffed together. When he questioned them, they told him they had been kidnapped, and were being held against their will in an apartment in the 6200 block of West Grand Avenue.

The off-duty officer called 25th District officers to the scene and when uniformed officers checked out the apartment involved, they got into an “armed confrontation” with a man inside, Guerra said.

An officer shot the suspect, a 41-year-old man who was taken to Advocate Illinois Masonic Medical Center in “very critical” condition, police and fire department officials said. He later was pronounced dead, according to police.

No officers were wounded in the shooting, and Guerra said the two kidnapping victims were not injured.

“No visible injuries. They seemed to be okay. They’re shook up, but they seem to be fine at this time,” Guerra said.

Chicago Police said they do not know if the suspect lived in the apartment where he was shot and killed.

A weapon was recovered at the scene.
