A San Francisco police officer suspected of driving while under the influence of alcohol was arrested Monday night following a car accident in Groveland that sent his passenger to the hospital.

Stanislav Bratchikov, 24, of San Mateo, was driving his 2002 Corvette west on Ferretti Road, just west of Pine Mountain Drive, at about 40 mph when he failed to maneuver through a left curve due to his intoxication, according to the California Highway Patrol.

Bratchikov went off the south shoulder of Ferretti Road in front of the Groveland Community Services District office and the right side of his Corvette clipped a pine tree, the report said.

The Corvette continued down the embankment before the right side smashed into another pine tree and came to a rest.

Bratchikov's passenger, Kevyn Rivera, 20, of Groveland, was transported to Sonora Regional Medical Center for a concussion and bruises, according to the CHP incident report.

Bratchikov was arrested on suspicion of felony DUI because of the injuries his passenger received. He was booked into Tuolumne County Jail.

San Francisco Police Sgt. Michael Andraychak confirmed that Bratchikov is currently employed as an officer in the department's operations division, which handles patrol services as well as some investigations.

Bratchikov has been employed as a San Francisco police officer for more than two years, Andraychak said.

"We're awaiting an incident report from California Highway Patrol," Andraychak said. "After it's reviewed, the department will make a determination on his work status."

The Tuolumne County District Attorney's Office said Bratchikov posted $25,000 bail and was released from custody. He is scheduled to be arraigned Aug. 1 in Tuolumne County Superior Court.
