A female passenger is in custody after an incident at the Greater Moncton International Airport on Saturday afternoon.
Codiac RCMP said they received a call from airport staff around 1 p.m. about a woman on a flight from Toronto acting strangely.
As police evacuated the arrivals area they isolated a piece of luggage they say belongs to the woman.
Traffic was diverted away from the airport and some passengers who arrived by plane at that time were kept on the tarmac for a couple of hours.
Police said a bomb squad will examine the luggage, but in the meantime airport operations have returned to normal.
The investigation is ongoing and no charges have been laid.
