Air Canada says a flight bound for Germany made an unscheduled landing in Montreal following an altercation between two passengers.
Air Canada spokesman John Reber says the incident occurred Wednesday night on a flight headed to Frankfurt from Toronto.
Reber says police were waiting when the plane landed at Pierre Elliott Trudeau International Airport at about 7:30 p.m. local time. One passenger was taken into custody and the flight departed at 8:40 p.m. local time.
Police spokesman Const. Olivier Lapointe says a Toronto man is in custody and is expected to be charged with causing a public disturbance.
Reber says the other passenger remained on the flight.
