A Sunwing Airlines flight headed to Cuba was forced to turn back to Toronto鈥檚 Pearson airport Wednesday after an apparent disruption by two passengers.

In a statement, Sunwing spokesperson Janine Chapman said the flight turned back after two 鈥渦nruly鈥� female passengers allegedly became disruptive after they had 鈥渃onsumed a significant quantity of their duty free alcohol purchase in the plane鈥檚 lavatory.鈥�

Chapman said the passengers lit a cigarette, triggering a smoke alarm, before getting into a 鈥減hysical altercation with each other.鈥�

The pair also allegedly made a 鈥渢hreat against the aircraft, which was considered non-credible given their condition,鈥� Chapman said.

NORAD confirmed Wednesday night that two Canadian fighter jets escorted the passenger aircraft back to Toronto鈥檚 Pearson International Airport as 鈥渁 precautionary measure.鈥�

Earlier reports suggest the plane was near Florida when it had to turn around.

Police said two women, both in their mid-20s, were arrested and remain in custody. Charges are pending as investigators interview witnesses, Peel police said.

Sunwing Airlines Flight 656 departed at 4:30 p.m., and was en route to Varadero via Manzanillo de Cuba Airport.

NORAD said in the statement that once the aircraft was safely on the ground, the CF-18 fighter jets returned to their home base in Bagotville, Que.

Sunwing said the flight was scheduled to take off again from Pearson at approximately 11 p.m. with a new flight crew.

This is the second time in just over a month that a plane travelling from Toronto has been forced to turn back. On July 25, a Panama-bound plane returned to Pearson Airport after a passenger allegedly made threats while aboard the aircraft.

The man was escorted off the plane by a tactical team of police officers. He was charged with counts of mischief, endangering safety, and uttering threats.

That incident also took place on a Sunwing flight.
