Sheriff's deputies say there are two suspects who allegedly came into the bank, displayed a weapon and stole an undetermined amount of cash.
The first is described as a 20-year-old black male, 5'8", 180 lbs, stocky build, wearing a black t-shirt. The second suspect is described as a black male, 6'1" to 6'2", 185 lbs, thin build, and wearing a black skull cap jacket and dark jeans.
Deputies say the suspects' vehicle left the scene going westbound on Business 20. It is described as being a newer champaign or beige colored vehicle with a spoiler on the back. The vehicle is the same type as a Chevrolet Malibu.
The Boone County Sheriff's Department and Rockford FBI are continuing to investigate the incident.
