Late Saturday night in the Englewood neighborhood in Chicago, a police officer was shot dead and another one sustained critical injuries.

The incident happened at approximately 9 pm local time, when the officers pulled over a vehicle in the 6300 block of South Bell Avenue, near West 63rd Street.

The officers were with the Chicago Police Department's Community Safety Teams unit. At some point during the encounter, the officers were fired at and sustained gunshot wounds, CPD officials said.

The officers returned fire, striking a male suspect. Two others who were inside the vehicle at the time, a man and a woman, were apprehended at the scene, according to CPD 1st Deputy Superintendent Eric Carter.

Both officers were rushed to the University of Chicago Medical Center where one was later pronounced dead.

The female officer was 29 years old, authorities said, but her name had yet to be released as of early Sunday. 

The officer is the city's first to be shot and killed in the line of duty since November 2018 when Officer Samuel Jimenez was fatally shot by a gunman who opened fire at Mercy Hospital, also killing two others.

Speaking at a news briefing in the hours following the shooting, Mayor Lori Lightfoot said the officer who died was "very young on the job, but incredibly enthusiastic to do the work."
