The Knoxville Police Department is investigating the attempted armed robbery of the Kum & Go store on East Main Street in Knoxville. Sources tell KNIA/KRLS news that an armed man came into the store, forcing the clerk outside before he fled to the wooded area to the north of the store near the bridge over the railroad tracks. The Iowa State Patrol assisted in the search for the man. This story continues to develop, and KNIA/KRLS will provide more information as soon as it becomes official.
