A passenger on an IndiGo flight from Mumbai to Kolkata on Friday was detained by the police after he was seen in a video purportedly slapping another person — who was reportedly suffering a panic attack — while on board the same flight.

The incident took place on IndiGo flight 6E138, an Airbus A321 aircraft. A video soon surfaced on social media, prompting sharp reactions and criticism.

According to IndiGo, the man was handed over to the authorities immediately after the flight landed in Kolkata. The airline said it has also initiated the process of filing an “incident report.” The incident will be reviewed by a committee to determine if the passenger should be put on a “no-fly” list. The Directorate General of Civil Aviation has also been informed of the matter, the airline said.

A senior officer with the Bidhannagar Police said, “The passenger was detained and later released.” In a post on X, IndiGo condemned the passenger’s “unruly behaviour”, adding that  such actions are “completely unacceptable.”
