What Happens in Vegas’ star Dennis Farina has issued an apology for his arrest on Sunday. The 64-year-old actor was arrested at Los Angeles International Airport after security discovered a loaded, .22 caliber, semiautomatic, pistol in his carry-on bag.

“I apologize to anyone and everyone that I have caused an embarrassment or inconvenience to,” Farina said. “It is my own stupidity to find myself in this embarrassing situation.”

The former Chicago police officer was charged with felony weapon possession. The charges were initially a misdemeanor, but were upgraded after authorities discovered that the gun was not registered.
