PHILADELPHIA (AP) - Investigators say a flight attendant forgot to take a gun out of her purse before leaving for work and the gun fired at Philadelphia International Airport as a police officer was trying to remove the bullets.

Philadelphia police Lt. Ray Evers says Transportation Security Administration officers noticed the gun Sunday and alerted police. Evers says a police officer tried to make the weapon safe by removing the bullets, but instead accidentally fired it. No one was hurt.

Investigators say the flight attendant has a valid gun permit. She has been cited for passing the gun through a security checkpoint.

Evers says the discharge is being investigated by Internal Affairs and the officer who accidentally discharged the gun will go back to training on handling weapons.
