4 injured in car accident involving CPD squad car

CHICAGO (WLS) -- A Chicago Fire Department spokesman says a pregnant woman and three Chicago police officers were injured when a squad car collided with two civilian vehicles at 41st and King Drive.

The woman, who is eight months pregnant, was transported to Mercy Hospital, fire officials said. Officials say the woman was a passenger in one of the two civilian vehicles. Her car was hit by an SUV that Chicago police were pursuing.

The woman's mother says her daughter is being treated for her injuries and is expected to recover.

Officials say two people were taken into custody after the accident. Police have not commented on why the squad car was chasing the SUV.
