A former New York City police detective has been arrested after officials said they found a fake bomb in his carry-on luggage at the Kansas City airport in Missouri, reports ABC News. The device had components of a bomb but not explosives or a detonator, officials said. When security guards questioned the unidentified man about the bag, he reportedly responded: "Open it, you'll get a big surprise." He hasn't offered any explanation yet for the contents.
