ST. PETERSBURG, Fla. (AP) — An Indiana man was arrested after authorities say security personnel at St. Petersburg-Clearwater International Airport found a gun in his bag.

The Pinellas County Sheriff’s Office reports that 57-year-old Michael Shelton was on his way to board a plane to Fort Wayne, Ind., Thursday when screeners spotted the gun on an X-Ray image of his bag. Transportation Security Administration searched the bag and reported finding a 9mm Smith & Wesson pistol.

Deputies responded to the airport, and Shelton reportedly told them he forgot the weapon was in his bag. Shelton was arrested and charged with carrying a concealed firearm. He was later released on $5,000 bail.

Jail records didn’t say if Shelton had an attorney.
