HELENA, Mont. -- An unruly passenger who was removed from an Amtrak train later made a threat that led to the train’s evacuation, an Amtrak official said Tuesday. Amtrak spokesman Marc Magliari said Hussein Abdi Hassan, 24, was removed from the train in Browning shortly before 8:30 p.m. Monday. While being interviewed by authorities, the Minnesota man “somehow threatened the safety of the train," he said. Nothing dangerous was found. The train was stopped between Browning and East Glacier. Passengers were taken to a middle school in Browning, where they were set up with sleeping bags and air mattresses.
