Authorities say it happened after a traffic stop. Sohn was a passenger in the vehicle. The sheriff's office says a K-9 detected the smell of drugs, and a purse with cocaine and drug paraphernalia was found after a search.
Bail was set at $1,500 for the 55-year-old actress, and she was released from the county detention center. An arraignment is scheduled for Tuesday. Sohn also has had roles in TV series including "The Chi," and "The Originals."
