Rs 4.5 crore cash, largely deposits in savings bank accounts, have been withdrawn in panic from the Kayalpattinam branch of the Central Bank of India in Tamil Nadu's Tuticorin district since Saturday - a figure that is six times higher than normal. An advertisement on January 11 that called for mandatory submission of National Population Registry letter as part of its Know Your Customer or KYC drive has touched a raw nerve and those opposing the contentious Citizenship Amendment Act (CAA), National Register of Citizens (NRC) and National Population Register (NPR) are protesting this way. Many say they are also scared that their money could be blocked.
