"I apologize to anyone and everyone that I have caused any embarrassment or inconvenience to," the 64-year-old actor said in a statement. "It is my own stupidity to find myself in this embarrassing situation."

When the weapon was discovered at a security checkpoint at about 8 a.m. Sunday, police said Farina told them he had forgotten the .22-caliber handgun was in his luggage.

Farina was booked for investigation of carrying a concealed weapon, said Sgt. Dennis Beacham. When police discovered the weapon was not registered, the charge was upgraded to a felony and Farina's bail was increased from $25,000 to $35,000.

He was released Sunday night after posting bail, according to the Los Angeles County Sheriff's Department Web site.

Farina's latest film, the Ashton Kutcher-Cameron Diaz comedy "What Happens in Vegas," opened Friday.

Farina has starred in TV's "Law and Order" series and in such movies "Snatch" and "Get Shorty."

The actor is also a former Chicago police officer.
