TORONTO - An Air Canada flight was flown back to Toronto's Pearson International Airport on Wednesday night due to an "unruly passenger."

Peel Regional Police say a flight attendant was assaulted during an incident on board the aircraft and suffered minor injuries.

The flight was bound for Budapest, Hungary and a police spokesman says he believes the plane was as far east as Nova Scotia when the pilot turned around and flew back to Toronto.

The unidentified passenger was arrested once back at Pearson and police say he is expected to appear in court on Thursday to face an assault charge.

There was no immediate information about the man's age or nationality.
