two Detroit-area men, Ahmed Mohamed Nasser al Soofi and Hezam al Murisi, arrested at Amsterdam's airport after U.S. authorities found suspicious items in their checked luggage, including a cell phone taped to a Pepto-Bismol bottle and a knife and box cutter.
The pair were arrested Monday morning at Schiphol Airport after getting off a United Airlines flight from Chicago, where their decision to change their flight plans raised flags in the U.S. that they were potentially assessing the aviation system for a potential future terror attack.
