New Delhi, Dec. 21 -- A day after an off-duty Air India Express pilot allegedly assaulted a passenger at Delhi's IGI Airport, the ministry of civil aviation on Saturday said they have taken cognizance of the incident and directed the airline to ground the pilot with immediate effect. The ministry said a formal enquiry has been ordered and detailed reports have been sought from the bureau of civil aviation security (BCAS) and the central industrial security force (CISF). Delhi Police said they had not received any formal complaint in connection with the incident. "The Ministry of Civil Aviation has taken serious cognizance of the incident and directed the airline to ground the pilot with immediate effect. A formal enquiry has been ordered. Detailed reports have been sought from BCAS and CISF," the ministry responded to victim Ankit Dewan's post on X. After the incident on Friday, the passenger had shared his experience in a social media post along with a photo showing blood on his face. The staffer, Virender Sejwal, was suspended by the airline. "...it is clarified that no such matter has been reported to the police station either by @ankitdewan or by the airlines. The matter has come to the knowledge of the police through this social media post. Whenever a written complaint is filed, appropriate legal action will be taken," deputy commissioner of police (IGI) Vichitra Veer said. Dewan, in another social media post, said he was contacted by two officials from the Air India Express headquarters, who told him that the incident reflected the actions of an individual and not what the company stands for. "While the actions of the pilot do not reflect beliefs of the company, he was on official duty (entering as staff). Thus they cannot shirk responsibility. AIX has to publicly declare a date by which their internal probe will be complete," Dewan posted on Saturday. In the previous post, Dewan said he and his family were guided to use the security check that the staff uses because they had a baby in a stroller. An argument broke out with Sejwal and he assaulted him....
