ATHENS — The Greek police say they have arrested a suspect in the 1985 hijacking of a flight from Athens that became a multiday ordeal in which an American sailor was killed and dozens of Americans were held hostage.

A 65-year-old suspect was being held in the hijacking and a 1987 abduction, the police said Saturday. They did not release the name of the suspect, a Lebanese citizen, who they said was arrested on the island of Mykonos on Thursday.

The hijacking involved TWA Flight 847, which was commandeered shortly after takeoff from Athens on June 14, 1985, according to a police spokesman, Lt. Col. Theodoros Chronopoulos. The flight originated in Cairo and had San Diego set as a final destination, with stops scheduled in Athens, Rome, Boston and Los Angeles.

The hijackers seized the jetliner and forced its crew to make three stops in Beirut and two in Algiers. The hijackers killed a 23-year-old Navy diver, Robert Dean Stethem, and released the other 146 passengers and crew members in stages, the last after 17 days.
