Actor Robert Downey Jr.’s son was arrested on suspicion of drug possession in West Hollywood, California, a Los Angeles County Sheriff’s deputy said.

    Indio Falconer Downey, the 20-year-old son of the “Iron Man” actor, was arrested on Sunday afternoon with what authorities believe was cocaine and a pipe used to smoke it, Sergeant Dave Valentine said.

    Valentine said Downey was arrested after the car he was a passenger in was pulled over by a deputy. No one else in the car was arrested.

    Downey posted bail* of US$10,250 and was released shortly after midnight. His court date is set for August 29.

    Downey appeared in the 2005 crime comedy “Kiss Kiss Bang Bang” in which his father, who has also struggled with drug addiction in the past, starred alongside Val Kilmer.

    Downey Jr. said in a statement that he believes his son likely has genetic predisposition* to addiction.

    He is Downey Jr.’s only child with his first wife, Deborah Falconer. The pair were married from 1992 to 2004.
