SACRAMENTO, Calif. -- A fisherman was seriously injured early Monday along the Sacramento River when after another boat hit his boat and then fled the scene, police said. The victim was taken to University of California Davis Medical Center for treatment of head injuries, officials reported. Police are meanwhile searching along the river for a green and white waterski-type boat that left the area. The incident occured just before 3 a.m. when a boat sitting near the I Street Bridge was T-boned by another boat traveling along the river, police said. Four men were fishing in the boat when it was hit. The accident ripped off the boat's windshield and damaged the hull. Three men were standing near the back of the boat when it was hit, while the injured man was near the bow. Witnesses told police that the boat that left the scene was traveling on the river with another boat, but police said it was unclear if the two boats were racing. The fishing boat sitting by the I Street Bridge had safety lights on at the time of the accident, police said. Police said if caught, the driver of the boat that fled the scene could face a felony charge of hit-and-run.
