The passenger, identified as Ashraf Veetil (30), was about to board a Jet Airways flight to Dubai this afternoon when he was found carrying the notes in his bag.
"When his bags were checked, Veetil was found carrying Rs 2,000 notes worth Rs 28 lakh," an official of Chhatrapati Shivaji International Airport said.
These notes were kept inside his check-in bag, the official said, adding, "These bills were hidden inside a jeans pant, over which he had kept various items like cooker, toys and tissue papers".
