The key point here is: "Charges are unclear". What are they going to charge him with? Impersonating a pilot? That's not a crime. Buying a fake pilot's ID? That's not a crime, either? Seat upgrades? For crying out loud!
The whole language of the article is the representation of modern journalism. "Authorities also uncovered his pictures". They just checked his Facebook page!!! Comparing him to Frank Abegnale is absolutely stupid. Abegnale was prosecuted for check fraud, not impersonating a pilot or flying around the world. However, "the businessman is being interrogated by police and intelligence agencies". Which, as is traditional in India, involves a couple of bamboo sticks and torture-du-jour, and may eventually persuade him that he actually is a criminal.
