A Mundelein teenager was arrested Saturday after he reportedly pointed a replica rifle at passing vehicles in the area of Route 83 and Route 53 in Long Grove.
According to the Lake County sheriff's office, deputies responded around 3:20 p.m. to a report of a person armed with a gun.
The 911 caller reported seeing a passenger inside a Honda Accord wearing a mask and armed with a rifle.
The caller said that as the Honda traveled north on Route 83, the passenger pointed a rifle at him and other vehicles on the roadway.
As deputies were responding, the sheriff's office notified Mundelein police, since the Honda was traveling toward Mundelein.
Mundelein police officers located the vehicle and conducted a traffic stop in the area of East Orchard Street and Route 45.
Deputies arrived and determined the rifle was a toy replica M16 rifle.
The 17-year-old boy was taken to the Hulse Juvenile Detention Facility. He was petitioned to juvenile court on three counts of aggravated assault.
