California Gov. Arnold Schwarzenegger and his son, Patrick, received minor injuries Sunday afternoon in a motorcycle accident near their Brentwood home, the governor's press secretary said in a written statement.

The low-speed collision occurred about 3:15 p.m. as Schwarzenegger was riding his Harley-Davidson with his son, Patrick, in the motorcycle's sidecar, according to Margita Thompson, the governor's press secretary.

As the pair were riding north on Mandeville Canyon Road, a car backed out of a driveway in the 2100 block and the governor was unable to avoid striking it, according to Thompson and a spokesman for the Los Angeles Police Department, which investigated the accident.

With a security detail from the California Highway Patrol, Schwarzenegger and his son were taken to St. John's Hospital in Santa Monica. Both were released after being treated for minor cuts and bruises, Thompson said. She added that the governor received 15 stitches in his lip.

The governor and Patrick, the older of his two sons, were wearing helmets at the time of the accident, Thompson said.

The driver of the car, she added, was not injured. Authorities would not release the driver's name. The California Highway Patrol referred calls about the accident to the LAPD.

LAPD Officer Jason Lee said no one was cited.

"It was an unfortunate accident," he said. "Thank God the governor and his son are OK."
