The West Bengal government declassified 64 closely-guarded files on Netaji Subhas Chandra Bose at an event at a police museum in Kolkata on Friday.
According to reports, Netaji Subhas Chandra Bose died in an air crash in Taiwan in 1945. But many of his relatives, friends and followers have disagreed with this narrative, forcing the Indian government to commission three different inquiries into the event between 1956 and 1999.
Bose's family members and researchers have repeatedly maintained the secret files lying in Delhi are of significance, as they contain the answer to the key questions on the disappearance of the firebrand leader and the subsequent years.
A lot of conspiracy theories have cropped up about Netaji's death - some say he escaped to Japan, some claim he lived as a sadhu in North India.
