An American Airlines spokesman said they received suspicious information about a passenger on board Flight 4117 from Chicago. Airline officials said the passenger was not on any watch list, but was ruled a potential security risk. As a precaution, the TSA ordered the pilot to land at Dulles.
TSA spokesman Greg Soule told the Associated Press the agency was notified of "a passenger acting unusually" and then rerouted the flight to Dulles. Soule said TSA and law enforcement officials interviewed passengers, who were all cleared. No hazardous materials were found on the plane.
Rob Yingling of the Metropolitan Washington Airports Authority said nobody on the flight was charged.
There were 45 passengers on board the flight -- many were bused to Reagan National.
