Officials say a suspicious note was found in the bathroom of a Virgin Atlantic flight to Boston.
Phil Orlandella, a spokesman for Logan International Airport, says the note was found Sunday in Flight 11 from London's Heathrow Airport to Boston. He says the note referenced a bomb and was found by a flight attendant.
The flight carrying 200 passengers and 16 crew members landed at Logan at around 6 p.m.
After passengers got off the plane, state police troopers with K-9 units and FBI agents searched the plane. The passengers and their bags were screened. Nothing was found.
Authorities say they do not believe the threat is credible because the note was dated more than a month ago. The investigation continues.
