Hollywood tough guy Dennis Farina was arrested on May 11 at Los Angeles International Airport trying to board a plane with a loaded gun. He was released on $25,000 bond and was "apologetic and cooperative," according to police.

Dennis Farina, a former policeman who built a Hollywood career playing detectives, was arrested Sunday at Los Angeles International Airport for carrying a loaded gun on his way to board a plane, police said.

Farina, 64, told police he brought the .22 caliber, semi-automatic pistol with him on a drive from Arizona to Los Angeles and forgot it was in his briefcase when he tried to pass through airport security, police said in a statement.

He was scheduled to take a United Airlines flight to his home in Chicago.

"Farina was very apologetic and cooperative with officers," police said. "However, he had no apparent authority to carry a concealed weapon at the time of his arrest."

The actor was booked on one misdemeanor count of carrying a loaded firearm, and his bail was set at $25,000.

Farina was a Chicago police officer for nearly 20 years before taking up acting in the 1980s.

He has starred in movies such as "Get Shorty," "Saving Private Ryan" and "Sidewalks of New York" and is perhaps best known in the role of New York Detective Joe Fontana on the popular television crime series, "Law & Order."
