Three men and a woman were removed from the Spirit Airlines plane, which was about to take off to Chicago’s O’Hare International Airport, when a female passenger was seen watching a video that another passenger deemed “suspicious.”
"A passenger alerted a flight attendant of a passenger engaged in suspicious activity on board," a source told Reuters. The plane had not yet taken off, and returned to the gate. All passengers were evacuated
First Sergeant Jonathan Green, a spokesman for the Maryland Transportation Authority police, told Reuters that one of the four travellers were questioned and released.
Once the aircraft and all passengers luggage were cleared, the plane took off approximately three and a half hours later.
