BOSTON -- A plane was diverted to Logan Airport just after 10 p.m. Friday after a passenger on a transatlantic flight tried to break into the cockpit and was subdued by passengers, Massachusetts State Police said.

The incident was not terrorism, according to officials at Massport, the agency that runs the airport. The passenger, identified as Itay Atmor, may have been suffering from an anxiety attack, officials said.

Delta Flight 86 was en route from JFK to Tel Aviv over the Atlantic when Atmor stormed the cockpit, police said. Five passengers subdued Armor, an Israeli national, and secured him in a passenger seat.

The plane had left New York about two hours earlier.

Pilots from the Vermont Air National Guard were put on standby when the incident was first reported, but they were told to stand down by the crew on board the plane.

Anthony Black, a spokesman for Atlanta-based Delta Air Lines Inc., said Flight 86 had 206 passengers and 11 crew members aboard.

Atmor, 22, was charged with interfering with a flight crew and will be arraigned at East Boston District Court on Monday.

The plane was parked in an isolated area of the airport while the FBI and Massachusetts State Police boarded and searched the plane. It continued its flight to Israel about three hours after landing in Boston.
