A young man without a helmet crashed his skateboard Tuesday on a Hamilton street and was transported to a hospital in critical condition, a Novato Fire District official said.
Captain Robert LaCroix said the skateboarder was found on Bolling Circle at 3:05 p.m. in "an extremely altered state." A crew from the Hamilton fire station took precautions to protect the man against spinal injuries and transported him to Marin General Hospital.
A witness told investigators that the skateboarder was riding downhill on Bolling just east of Kelly Drive when he crashed and struck his head, LaCroix said.
The skateboarder did not have identification on him, LaCroix said, and estimated the man is in his 20s. The Novato Police Department was investigating the incident.
