Pittsburgh International Airport briefly closed its security checkpoints and the People Mover Trains after a hand grenade was found in a passenger's bag. Airport spokeswoman JoAnn Jenny says the shutdown lasted about a half an hour after what looked like a grenade was found in a departing passenger's carry-on bag. She says a bomb squad determined the grenade was inert at about 7:05 this morning and then re-opened the checkpoints and train.
Jenny says she doesn't know where the passenger was headed but he told security guards the grenade was inert. Police are questioning the passenger to determine why he was carrying the grenade.
