A woman aboard a British Airways plane from London to Boston has been arrested after trying to open the plane's emergency exit door during the flight, officials said.
The passenger on British Airways Flight 213, a Boeing 777, was restrained for the rest of the flight, and then arrested upon arrival at Boston's Logan Airport, the airline said.
"Our customers and crew deserve to have a safe and enjoyable flight and we do not tolerate abusive behavior," British Airways said in a statement, referring to the passenger as "an unruly customer on board."
Massachusetts State Police said the passenger "was intoxicated" and there was no connection to terrorism. The Joint Terrorism Task Force and the Transportation Security Administration also investigated the incident.
The incident came amid heightened fears about security, after Russian officials confirmed Tuesday that a passenger jet that crashed in Egypt was brought down by a bomb. Major cities have also been alert after the coordinated terror attack in Paris over the weekend that killed 129 people and injured more than 350 others.
