While towing a tube the operator of the boat throttled back to slow the boat down. As the tube that contained two occupants began to slow the front of the tube began to dip into the water on the front end of the tube.  As it did one of the tube riders fell of the front of the tube.  As the weight of the rider came off the tube it lurched forward, and the metal clip that had the rope tied to it caught the neck of the tube rider that fell off.  As the operator of the boat came back to the fallen tuber he could see blood in the water and blood coming from the tubers neck.  They immediately got him in the boat and started toward shore.  As they headed for the shore they called 911 and asked for an ambulance.  They transported the injured person by car to the entrance of Clinton Lake State Park to meet the ambulance.  CPO and I were then contacted by District 6 of the Illinois State Police about the accident.  We then went to the entrance and met with the injured tuber and his mother.  The ambulance was already on scene.  After an initial evaluation the tuber was transported by his family to Bromenn Hospital in Normal by his family to seek treatment for his injuries.
