An Air India pilot Saturday allegedly punched an engineer after an argument that led to the Chennai-Delhi flight getting delayed, an airport official said.
According to sources, the pilot punched the engineer on his nose after an argument and later locked himself in the cockpit.
The flight was delayed due to some technical reasons, and the pilot was not satisfied about the rectification of the snag and refused to fly.
This led to an argument and the alleged punching of the engineer.
The engineer with his nose bleeding was admitted to a hospital and his colleagues have threatened to go on strike.
The engineers demanded a police complaint against the pilot.
Sources said Air India has instituted a probe into the incident, and the pilot was derostered.
The flight took off with a new crew after a couple of hours.
