Operator 1 and operator 2 were operating their respective jet skis jumping the wakes of their own vessels and others doing donuts and spinout type maneuvers within several feet of each other. A lake authority officer observed the reckless fashion of their operation and conducted a vessel stop by utilizing the blue emergency lights on his patrol vessel. The lake authority officer approached the vessels and throttled down into a neutral position. Vessel 1 observed the patrol vessel approaching him with its emergency lights on and let off of the throttle of his vessel from a speed of approximately 35 mph and was within 15 feet of the patrol vessel's port bow.  Vessel 2 was operating at approximately 15-20 mph within 75-100 feet of operator 1 riding his wake. Operator 2 was too close to operator 1 and collided with the port side of vessel 1 impacting the rear grab bar and operator 1's left hip and leg area throwing him off vessel 1. Vessel 2 then drove over operator 1 as he went into the water. The seat and rear grab bar from vessel 1 were detached and floating in the water. The rear grab bar of vessel 1 was broken in two pieces.
