Investigations are ongoing as to how the passenger managed to exit Mumbai Airport after leaving the plane

Speaking to Indian news site Mid-day, airport officials have reacted with anger as to why it took Jet Airways staff 35 minutes to notify security.

A spokesperson said: 'If the incident took place after the aircraft landed, why didn't the airline security staff inform the security agencies immediately?'

The police's Airport Division have confirmed they are investigating the matter, and are still trying to trace the whereabouts of the 30-year-old man.

The plane, a Boeing 737 flight had 144 passengers and five crew members on board.
