London-to-Washington flight diverted to Boston

An overseas flight from London’s Heathrow Airport to Washington, D.C. was diverted to Boston today after the pilot declared an emergency because of a passenger disturbance, the airline said.

A female passenger aboard United Flight 923 had Vaseline, a screw driver, matches and a note referencing al-Qaida, according to Phil Orlandella, spokesman for Boston’s Logan International Airport.
