No explosives found at Louisville airport after K-9 team detects something suspicious in cargo - DNJ No explosives were found at Louisville International Airport after bomb-sniffing dogs detected something suspicious on a cargo pallet Tuesday night, according to Louisville Metro Police. The police department's bomb squad assisted the Transportation Security Administration by X-raying packages, said police spokeswoman Alicia Smiley. Because nothing suspicious was found, she said it cannot be determined what caused the dog to signal an alert. The cargo facility where the pallet was located was evacuated, according to TSA spokeswoman Sari Koshetz. United Parcel Service's air hub is at the Louisville airport, but the company's operations were not affected by the incident, said company spokesman Mike Mangeot.
