Police said officers responded to a call about a large gathering in the 300-block of East Balbo Drive, near Grant Park, just after 3 a.m.
There, officers saw a group of speeding vehicles and deployed a tire deflation device.
Police said one of the vehicles, a black sedan, went around the device and headed toward an officer.
That officer fired shots, striking the vehicle, but no one inside of it was hit by gunfire, police said.
The officer suffered a minor ankle injury and was treated and released from the hospital.
The sedan's driver was taken into custody.
No other injuries were reported. CPD's investigative Response Team is investigating.
The Civilian Office of Police Accountability is also investigating, and the office involved will be placed on routine administrative duties for a minimum period of 30 days.
