An Air Canada flight en route from Toronto to London had to make an emergency landing after its co-pilot apparently suffered a nervous breakdown, according to the Daily Mail.

The Boeing 767 was flying at 37,000 feet over the Atlantic Ocean when the unidentified co-pilot began shouting and "invoking God" and had to be restrained, the Daily Mail reported.

Crew members and a passenger, who happened to be in the armed forces, held down the man, shackling his wrists and ankles and tying him to a seat.

The flight made an emergency landing in Shannon, Ireland, and the co-pilot was taken off the plane crying and yelling, according to the Daily Mail.

He was being treated at a psychiatric ward for what was believed to be a nervous breakdown.
