SANTA MONICA, Calif. - Santa Monica police say actor Nick Nolte's son has been arrested on suspicion of driving under the influence of a controlled substance.

Sgt. Jay Trisler says 23-year-old Brawley Nolte was driving north on Pacific Coast Highway Tuesday afternoon when he made a lane change and struck a vehicle in front of him.

Officers called to the scene believed Nolte had been driving while impaired. Trisler says Nolte was arrested following a series of sobriety tests. He was freed after posting $5,000 bail.

Trisler did not immediately return a message seeking comment on whether Brawley Nolte has an attorney.

Brawley Nolte portrayed Mel Gibson's kidnapped son in the 1996 film "Ransom."

Nick Nolte pleaded no contest in 2002 to a misdemeanour charge of driving under the influence of drugs.
