Assault charge laid after London to Toronto flight diverted to Halifax

Nova Scotia RCMP have charged a 30-year-old South African woman with assault after an international flight from London to Toronto was diverted to Halifax.

Investigators said the Air Canada flight was travelling Wednesday from Heathrow Airport to Pearson International with 239 passengers on board when it made a sharp turn from its course to land at Halifax Stanfield International Airport.

Police allege two flight attendants were assaulted by an "unruly passenger."

Nobody was hurt, officers said.

The 30-year-old woman, who is from Sandhurst, was charged with three counts of assault on an aircraft, one count of assault with a weapon, one count of causing a disturbance and one count of endangering an aircraft under the Aeronautics Act.

She appeared in Dartmouth provincial court on Wednesday and was released on conditions after $10,000 was couriered to the court.

Her passport was seized by the Canada Border Services Agency and she must remain at a residence in Oakville, Ont., on a promise to keep the peace and stay away from alcohol and weapons.

She is set to return to court on Jan. 22 to plead to the charges.
