An Air Canada flight that left London, England, bound for Toronto was temporarily diverted to Halifax Wednesday after a female passenger allegedly assaulted two flight attendants.

Air Canada confirmed in a tweet that Flight 869 was diverting in Halifax due to an "unruly passenger." The flight touched down in Halifax at about noon local time, and took off for Toronto just before 3 p.m.

After the plane landed at the Halifax Stanfield International Airport, RCMP officers boarded the aircraft and arrested a 30-year-old South African woman, Sgt. Alain LeBlanc said in a statement.

"The preliminary investigation indicates that a female passenger allegedly assaulted two flight attendants during the flight," he said. "The woman was arrested and is in police custody. The investigation is ongoing."

AC Flight 869 flies direct daily from London's Heathrow Airport to Toronto's Pearson International Airport.

The diversion comes after several high-profile disruptive air travel incidents this year.

On Monday, an executive for Korean Air publicly apologized for causing a delay on a flight when she ordered a crew member off the plane for serving her bagged macadamia nuts in first class rather than nuts on a plate.

And last week, a Thai AirAsia flight was forced to return to Bangkok after a passenger allegedly assaulted a flight attendant by tossing hot water at her.

In a statement from Thai AirAsia, the airline said the passenger berated the attendant before scalding her with water. The attendant was given first aid, while the plane returned to Bangkok.

A high-profile Canadian case caught international attention in August, when a Sunwing flight headed for Cuba was forced to return to Toronto after two female passengers allegedly consumed "a significant quantity" of duty free alcohol in the plane's washroom.

A company spokesperson said the two women also allegedly lit a cigarette, triggering the smoke alarm, then proceeded to get into a "physical altercation" with each other.

Two Canadian military jets accompanied the Sunwing plane back to Pearson airport, and the two passengers were arrested once the aircraft landed in Toronto.
