The I-290 expressway was closed in both directions early Sunday morning after a crash around 2 a.m. Investigators said the drivers of two vehicles exited their cars and began arguing.
“A good Samaritan on scene alerted officers that one of the subjects had a gun,” said a statement from Sophia Ansari of the Cook County Sheriff’s Office.
The suspect, a driver from one of the cars, fled on foot with sheriff’s officers giving chase. Meanwhile, local police closed the highway between Harlem Avenue and First Avenue.
During the foot chase, one of the officers fired his handgun the man suspected of carrying a weapon, but the suspect was not hit, Ansari said.
The suspect was taken into custody by sheriff’s police and transported to Loyola Medical Center for injuries sustained in the accident, Ansari said. Police did not release any other information about the man taken into custody.
The Cook County Sheriff’s Office did not identify any other people injured in the accident.
The highway reopened around 5 a.m. Sunday.
