The driver exited the vehicle and tried running away before Rockford police swarmed him. A passenger was also arrested, police said. The men are believed to be 36 and 25 years old, according to officers.
Both are at a Rockford area hospital with minor injuries, police said.
Officers began pursuing the car at around 3:15 p.m. after the driver allegedly pointed a gun at another motorist in Forest Park.
Forest Park police pursued the silver Dodge Charger onto the Eisenhower Expressway, where Illinois State Police joined the pursuit.
Charges are pending against both men.
