A teenage actress — who alleged she was harassed by a male passenger on a Vistara flight — and her mother refused to file a complaint upon their arrival at Mumbai airport from Delhi, the airline said in its official response on the matter, which blew up on social media last weekend.Vistara said the crew did not observe any misbehaviour by the male passenger during the flight in a two-page letter to the Directorate General of Civil Aviation DGCA ), the aviation ministry and the National Commission of Women. ET has seen the letter. Police arrested the male passenger after filing a case based on a social media post by the teenager, who is a minor.“He kept nudging my shoulder and continued to move his foot up and down my back and neck,” she said in the video post. “Is this how we are going to take care of girls?” The crew only became aware of anything untoward at the time of landing, when the actress shouted, Vistara said.“During the flight, until the touchdown, the Vistara crew did not observe any misbehaviour, and was not informed by any person,” the airline said. “At one point during the final descent of the flight into Mumbai airport, when the aircraft was in 'sterile mode' where crew cannot leave their seats as per required safety procedures, the crew hears (the teenager) speak loudly to the person seated behind her, but the crew was not aware of the subject matter of this discussion.” There was no response to text and WhatsApp messages sent to the actress.Vistara said the teenager didn’t respond when a crew member asked if she was alright as the plane was taxiing after landing. The airline said it asked the actress and her mother whether they wanted to file a complaint or first information report (FIR) but they refused. The letter points out that, as the girl is a minor, “we complied with the guidance/instruction of her parent with regard the FIR.”
