A series of fights shut down the National Cattle Congress Fair Saturday night. Waterloo Police used pepper spray to break up the fights. While reports say witnesses saw firearms, police say no shots were fired. Later, a youth was shot in a nearby neighborhood. It wasn’t immediately clear if the shooting was connected with the fights at the fair. Police say they broke out shortly before 10pm Saturday. Officers worked to disburse crowds and the fair was shut down. After closing down the fair, officers were then called to the 800 block of Riehl Street around 10:30 PM. Officers said a 12-year-old boy had been shot in the arm. This was about a mile from the fair grounds. The boy was taken to UnityPoint-Allen Hospital for treatment. Police continue to investigate both the shooting and the fights.
