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.
