An Uxbridge man was due to be arraigned in East Boston court Thursday after allegedly making a false bomb threat on a plane at Logan International Airport.

State Police boarded United Airlines flight #439 at about 6:50 p.m. Wednesday following a report of a man making threats about a bomb in his bag. Passengers heard him making these statements regarding the potential bomb and called for help.

These threats proved to be bogus, but the flight was delayed nearly an hour as authorities investigated the situation.

Troopers arrested Dennis Campbell, 55. He was booked at the State Police Barracks at Logan Airport and was held on $250 bail.
