On 24 May 1971, based on a telephone call purportedly from Prime Minister Indira Gandhi and her secretary P.N. Haksar, the chief cashier at the Parliament Street branch of the State Bank of India handed over Rs 60 lakh to a stranger posing as the PM's courier. The money was supposedly meant for secret operations in East Pakistan. When the chief cashier approached the PMO for a receipt, he was told that neither Haksar nor the PM had given any such instructions. He had been duped.
