In other news, family members of Netaji Subhas Chandra Bose have appealed to Prime Minister Narendra Modi to form a Special Investigation Team for solving the mystery behind the nationalist leader's disappearance.

In a letter written to Modi from the Open Platform for Netaji, the family members said that an SIT should be constituted under the guidance of a sitting judge of the Supreme Court to investigate into the matter.

"The SIT would include professionals from all relevant fields of expertise eg Central Home Department, Intelligence Bureau, Central Bureau of Intelligence, External Affairs Ministry, historians and researchers. The SIT would scrutinies all the declassified documents and interview/cross examine witnesses and concerned persons," the letter said.

Netaji's grandnephew Chandra Kumar Bose told PTI that they have also sought an appointment with Modi next month to press for their demands.
