A woman charged in connection with an alleged bomb threat at the Greater Moncton International Airport last weekend has been sent for a 30-day psychiatric assessment.

Tiffany Van Allen, 26, of Moncton, made a brief appearance in provincial court on Wednesday.

She had been facing a charge of hoax for allegedly relaying information that could raise apprehension about terrorist activity, but that charge has been dropped.

She is now charged with two counts of mischief.

Codiac Regional RCMP were called to the airport on Nov. 16 at about 1 p.m. regarding a bomb threat.

Police said a woman, who was destined for Toronto, made some kind of comment or statement while going through security that prompted her arrest.

The arrivals area was subsequently evacuated and the airport was shut down for about three hours. Traffic was diverted away and several planes were delayed.

The woman's luggage was isolated and checked by the RCMP's explosive disposal unit, but no explosive device was found, police said.
