People were forced to evacuate from several terminals at Los Angeles International Airport Saturday due to a bomb threat. The FBI arrived at the airport around two Saturday afternoon after they received a call about an explosive device inside a homeland security vehicle. The vehicle was parked in one of the airport’s lower terminals and a bomb squad investigated the threat around the perimeter, but found nothing. The evacuation was lifted around 4 p.m. Saturday afternoon. Airport officials expected heavy traffic delays as everything returned back to normal.
