An inebriated man onboard an Air India flight urinated on a woman co-passenger and a senior citizen, seated in a business class seat.
Aviation regulator DGCA on Wednesday said it has sought a report of the incident from the airline.
The watchdog also said it will take action against those found negligent with respect to the incident, while Air India has set up an internal committee to look into the matter and decide on appropriate action.
