Authorities Find Nothing Suspicious After Evacuating Louisville International Airport

LOUISVILLE, Ky. -- Louisville police bomb experts found nothing suspicious after a dog trained to sniff for explosives reacted to a pallet at a remote cargo facility at Louisville International Airport.

Transportation Security Administration spokeswoman Sari Koshetz says after the dog alerted officers at around 7 p.m. Tuesday, the facility was evacuated and explosives experts were brought in. She says the airport closed one runway as a precaution.

Louisville police spokeswoman Alicia Smiley said a bomb squad examined packages for about two hours but found nothing.

The animals are trained to signal if they believe they detect explosives, but officials note an alert can be given for materials that aren't dangerous.
