Officer Peter van Eckhardt said late Monday that the 26-year-old Lynch was arrested early Saturday in the city of Emeryville.
Lynch was taken to the Santa Rita Jail, where he was cited and later released. Van Eckhardt says Lynch took a chemical test but it wasn't clear whether that was a blood or breath test.
Van Eckhardt says the test results will be forwarded with the rest of the arrest information to the Alameda County district attorney's office. He says he has no details of the arrest.
The Seahawks said a statement Monday that the team is "aware of the situation with Marshawn and still gathering information."
Lynch signed a four-year contract in March that will keep him in a Seattle uniform for the prime of his NFL career and is coming off his finest season.
Lynch rushed for 1,204 yards and 12 touchdowns last season and embodied the attitude head coach Pete Carroll wanted the rest of his roster to emulate. Lynch had stayed clear of trouble with the Seahawks since coming to Seattle during the 2010 season.
In June 2008, he pleaded guilty to a traffic violation and admitted to driving off after striking a female pedestrian with his car near the downtown bar district in Buffalo, N.Y.
In March 2009, Lynch pleaded guilty to a misdemeanor gun charge in Los Angeles, after police discovered a semiautomatic handgun in a backpack located in the trunk of a parked car Lynch was sitting in.
