Netaji Subhash Chandra Bose is believed to have died in an air crash in Taiwan on August 18, 1945.

India has made several requests to Russia since 2014 seeking information on Netaji Subhash Chandra Bose, but Moscow has conveyed that it was unable to find any documents in the Russian archives pertaining to the freedom fighter, the Lok Sabha was informed on Wednesday.

In a written reply to a question in the Lok Sabha, Minister of State for External Affairs V Muraleedharan said India sought information on Netaji such as whether he was in Russia any time before or after August 1945 and whether he escaped to Russia in August 1945 or thereafter as reported by some researchers.

The Indian government, in several requests since 2014, sought documents or material relating to Netaji, which may be in the custody of the Russian side, he said.

"In its response, the Russian government has conveyed that they were unable to find any documents in the Russian archives pertaining to Netaji and even after additional investigations made based on request from the Indian side, they could not find any documents giving more information on the subject," Mr Muraleedharan said.

Netaji Bose founded Indian National Army, also known as the Azad Hind Fauj, in 1942 to fight British with the support of Japanese forces.

Netaji is believed to have died in an air crash in Taiwan on August 18, 1945.
