The Pottawattamie County Sheriff's Office says it has received numerous reports of logs, trees, rocks, branches and fishing line placed on the Wabash Trail in Council Bluffs.
The debris on the trail caused a biker to be thrown from their bike and injured during the Taco Ride on Aug. 9.
Three juveniles have been arrested and charged with harassment in the third degree in juvenile court.
The Wabash Trail extends more than 40 miles and passes through Malvern, Silver City, Mineola and Shenandoah.
