A Glidden teenager was seriously injured in an ATV accident Easter Sunday. The Carroll County Sheriff’s Office reports they responded to Velvet Avenue, south of U.S. Highway 30 at approximately noon. A 17-year-old male was operating a 2003 Suzuki ATV northbound and as he traveled under the railroad overpass and negotiated a curve, he crossed the centerline, going too far to the left side of the road. Authorities believe the left tires struck a buildup of gravel, which caused the ATV to flip. The juvenile was transported to St. Anthony Regional Hospital by Carroll County Emergency Medical Services and later transferred to a Des Moines hospital.
