An Alberta man is facing charges after a flight attendant was assaulted early Wednesday, forcing an Air Canada flight bound for New Delhi to return back to Toronto.

Police say a 47-year-old man was arrested and charged after “assaultive and belligerent behaviour towards a flight attendant” while aboard Flight AC70.

Witnesses said the disruptive passenger used abusive language during the incident, which happened just after 12:30 a.m., as the plane was travelling over the east coast.
