Illinois State Police are investigating multiple reports of vehicles damaged by what may have been a pellet gun while driving on the Eisenhower Expressway from the West Side to the western suburbs this week.
The incidents were reported along I-290 between Central Avenue in the Austin neighborhood and 17th Avenue in Maywood, according to a statement from ISP.
Two vehicles were hit by “foreign objects” between 7-7:30 p.m. Wednesday, police said. One was in the eastbound lanes while the other was westbound.
The driver of the eastbound vehicle was struck in the arm but not injured, according to police.
The next day, two other vehicles were hit between 6:25-6:45 p.m., police said. One was westbound near East Avenue in Oak Park, while the other was westbound near Central.
Authorities believe the vehicles may have been shot with a pellet gun, but that has not been confirmed, police said.
