An airline spokeswoman said flight WG604 had departed for Cayo Coco but turned around due to the passenger making “non-specific threats.”
“The flight arrived back around 7:25 p.m. and the disruptive customer was taken into police custody,” Rachel Goldrick said in an email to The Canadian Press.
The passenger’s name was not released, nor was the specific nature of the threats.
NORAD spokesman Lt. Commander Joe Nawrocki said a pair of U.S. Air Force F-15 jets were dispatched from Barnes Air National Guard Base in Massachusetts and intercepted the aircraft near Albany, N.Y.
Canadian CF18s were also reportedly scrambled but did not take part in the operation.
Goldrick said it would early Friday before the 170 passengers would be able to board the next flight to Cayo Coco.
“Sunwing has provided affected customers with accommodations and meal vouchers and is very apologetic for the inconvenience.”
WATCH: American Airlines pilot takes down unruly passenger
This was the second such incident involving a North American flight on Thursday night.
Officials say a Delta Airlines flight bound for Beijing returned to Seattle-Tacoma International Airport after a passenger assaulted a flight attendant.
Airport spokesman Perry Cooper says a man in first class assaulted a flight attendant about 45 minutes into the flight and that passengers then helped restrain the man until the plane landed back in Seattle.
Officials say two people, including the flight attendant, were injured and taken to a hospital.
Montreal police say the suspect was arrested and is expected to appear in court Friday, where he could face charges of public mischief and several counts of uttering threats.
