Dennis Farina has been arrested at Los Angeles International Airport after a loaded gun was found in his carry-on luggage.
Police say the 64-year-old actor told them he forgot the .22-caliber handgun was in his luggage Sunday.
Sgt. Dennis Beacham says Farina was caught at a security checkpoint and booked for investigation of carrying a concealed weapon. Bail was set at $25,000.
Messages were left for Farina's attorney, Kevin York, and his agent.
Farina has a role in the Ashton Kutcher and Cameron Diaz comedy "What Happens in Vegas." It opened Friday.
He has also starred in TV's "Law & Order" and in the movies "Snatch" and "Get Shorty."
