A 20-year-old Lakeport man suffered major injuries and was arrested early Saturday after a vehicle crash that also injured a 17-year-old female passenger.

Michael Dale Bryant was arrested before he was transported by REACH air ambulance to Kaiser Hospital in Vacaville, according to a CHP press release issued Wednesday.

The press release didn’t list the charges but stated that “alcohol was determined to be a factor in the collision.”

The crash occurred about 12:45 a.m. on Lakeshore Boulevard just north of Deer Hill Lane. Bryant was heading south when he lost control of his pickup as it came out of a curve.

Bryant, who wasn’t wearing a seatbelt, was partially ejected after the truck struck a post, ran into a ditch and came to rest on its roof. He suffered injuries to his right arm, shoulder and head.

His passenger was wearing a seatbelt but still suffered major injuries to her head and face. She was taken first to Sutter Lakeside Hospital in Lakeport and later to UC Davis Medical Center.
