The boy went through
security with all other passengers, the Transportation Security
Administration said in a statement, but officials are still trying to
figure out how he did it -- and how he then got on the flight.
Patrick Hogan, a
spokesman for Minneapolis-St. Paul International Airport, said the crew
of Delta Flight 1651 "became suspicious of the child's circumstances"
during the flight from Minneapolis to Las Vegas. Crew members got in
touch with authorities in Las Vegas and turned the boy over to Child
Protective Services, Hogan said in a statement.
"Fortunately, the flight
crew took appropriate actions to ensure the child's safety, so the story
does have a good ending," he said.
