RedactedNarrative: While on uniformed patrol at Buck Creek State Park we received a call from the ODNR Dispatch Communication Center that an adult male had a possible broken arm from knee boarding just outside of the boat swim zone at Buck Creek State Park.  The boat that was being used in the accident was temporarily moored up to the beach when myself and other units arrived.  We mad contact with the victim and he stated that he was being pulled on the knee board when the knee board hit a wake and lost tension in the line.  While the line was loose his arm had gotten tangled in the line. The line then tightened up around his arm and was then drug by his arm in the water.  We got the victim attention and transported to Springfield Regional Hospital.
