Rafindadi in his deposition to the Oputa Panel in November 2000 alleged that even before the NSO had commenced their investigations, Babangida brought a letter to the late Major-General Tunde Idiagbon, then chief of staff, Supreme Headquarters. The letter was supposed to be a clearance letter for the project under investigation purportedly written by the previous DG of the NSO, Umaru Shinkafi. Upon examination by the NSO, it turned out that the letter was actually written during Rafindadi's tenure as DG NSO, the name of the officer that signed the letter was fake and the letter was declared as a forgery.
