Bachchan, who was to board Jet Airways flight 9W 202 for Pune at 9.55am, had declared his weapon as part of his check-in baggage, but the documents he produced for it turned out to be those of another of his three guns.
A passenger carrying a weapon has to declare it with documents to the airline before check-in. It is only after cross-checking the documents and the make of the weapon that the airline packs it into the registered or check-in baggage.
"Bachchan had declared the weapon to the airline. However, he later realised that the documents he was carrying along were not for the same pistol,'' said an airport source. "The pistol was later sent back with his secretary,'' he added.
