 CLEARWATER, Fla. (AP) - A southwest Florida woman has been arrested after authorities say security screeners found a handgun n her carry-on bag at St. Petersburg Clearwater International

The Pinellas County Sheriff's Office says Kristy Louise Grove, of Fort Myers Beach, was ready to board her flight to Chattanooga, Tenn., Saturday morning when the weapon was found.

Investigators say Grove told deputies she had forgotten the gun was in her bag. Grove was charged with carrying a concealed firearm. No working phone number for Grove could be located.
