Around two months ago, the Bengaluru Regional Passport Office (RPO) received a rude shock when two people who were issued passports from the office were arrested in West Bengal in separate cases. They were later found to be immigrants from Bangladesh. In these cases, they managed to get passports based on authentic documents such as PAN card, Aadhaar card and EPIC. But these were obtained illegally. Unique Identification Authority of India (UIDAI) officials, however, said Aadhaar is not proof of citizenship.
