ORLANDO, Fla. (AP) -- Authorities say a Florida firefighter who brought a handgun onto a flight out of Orlando will not be prosecuted.

The unidentified woman told authorities she forgot she had a 380-caliber semi-automatic in her purse when she boarded a flight Thursday.

The woman went through screening checkpoints at Orlando International Airport, but the gun was not detected.

The woman told authorities about the incident when she landed at Newark Liberty Airport.

A spokesman for the Port Authority of New York and New Jersey said officers confiscated the gun but did not charge her because she came forward on her own.

The Orlando Sentinel reports that Transportation Security Administration is reviewing the incident.
