INA treasure controversy: The INA treasure controversy relates to alleged misappropriation by men of "Azad Hind" of the "Azad Hind" fortune recovered from belongings of Subhas Chandra Bose in his last known journey.  The treasure, a considerable amount of gold ornaments and gems, is said to have been recovered from Bose's belongings following the fatal plane crash in Formosa(present-day Taiwan) that reportedly killed him, and taken to men of "Azad Hind" then living in Japan.  The Indian government was made aware of a number of these individuals allegedly using part of the recovered treasure for personal use.  However, despite repeated warnings from Indian diplomats in Tokyo, Nehru is said to have disregarded allegations that men previously associated with "Azad Hind" misappropriated the funds for personal benefit.  Some of these are said to have travelled to Japan repeatedly with the approval of Nehru government and were later given government roles implementing Nehru's political and economic agenda.  A very small portion of the alleged treasure was repatriated to India in the 1950s.
