VOLO, Ill. (CBS) — A man has been arrested on aggravated DUI and other felony charges, after slamming into a Lake County Sheriff’s squad car that was blocking traffic after an earlier crash on Monday near nort suburban Volo, injuring a deputy who was standing next to the cruiser.

Lake County Sheriff’s police said, shortly before 6 p.m. Monday, a 1995 Mazda convertible was heading south on Route 12 near Volo Village Road, when the driver crossed into oncoming traffic, and hit a 2005 Toyota sedan.
