Police are investigating an incident where five unidentified paragliders sparked a security scare at Mumbai's Chhatrapati Shivaji International Airport two days ago.
An Ahmedabad-bound Jet Airways flight had to abort take-off on 23 May, after its pilot spotted the paragliders in its take-off path.
The pilot then informed the air traffic controller (ATC) about the five small parachutes that were seen approaching the airport from its southwest direction.
The Indian Express quoted an airport official as saying: "Flight 9W 323 was about to takeoff, but after the airside security spotted some paragliders in the take off flight path, the takeoff was cancelled. Only one flight was affected."
A police officer told local media that the paragliders were spotted in the air around 6pm local time, and disappeared later on.
Two persons working for an event management firm were reportedly arrested on Monday for flying promotional air balloons near the airport.
However, the seniors in the police department have remained non-committal. They have been maintaining that a police post nearby the airport has not spotted any unusual activity in the vicinity.
Police, law and order joint commissioner Deven Bharti said the police have not found any concrete clue about the incident.
Jet Airways, too, has denied receiving any such information.
Flying of drones, remote-controlled aerial missiles, paragliders and remote-controlled micro-light aircraft have been prohibited by the city police after central intelligence agencies warned about the possibility of a potential airborne terrorist attack in Mumbai.
