5 EYEWITNESS NEWS has learned that federal investigators and airport police are questioning six Middle Eastern men who had to be escorted off of a plane Monday afternoon at Minneapolis/St. Paul International.

U.S. Airway officials tell 5 EYEWITNESS NEWS Aviation Expert Bob McNaney that Monday while Flight 300 was preparing to take off from Minneapolis to Phoenix, a passenger passed a note to a flight attendant saying they noticed ‘suspicious behavior,’ among the men.

The men would not get off the plane when asked, 5 EYEWITNESS NEWS has learned, and had to be removed by police.
