At least two dozen vehicles were damaged Tuesday in a parking garage in the Loop.
About 6:15 p.m., officers responded to the 300 block of South Franklin Street where about 24 vehicles in a parking garage were damaged, Chicago police said. Someone had thrown a rock through the rear window of the vehicles.
The 24 vehicles were on different floors, police said. It was not clear whether any property was stolen.
