More than 10 months after former RAW joint secretary Rabinder Singh fled the country right under the nose of the establishment, the Government has given final shape to its Official Secrets Act case against him. The complaint could be filed in court as early as next week. Significantly, government agencies are also busy collating evidence for a second OSA case, to be filed later, against several other officials who are being described as Rabinder Singh’s ‘‘accomplices’’. There are indications that some of them may have been caught on surveillance cameras, helping Singh. Singh’s escape, first reported by The Indian Express, was followed by a long period of inaction. The Government’s latest strategy was finalised yesterday at a high-level meeting chaired by Cabinet Secretary B K Chaturvedi. Others who attended the meeting were the RAW Chief, P K H Tharakhan, Home Secretary Dhirendra Singh and Law Secretary R L Meena. Last week, RAW had sent its proposals to the Cabinet Secretary to take criminal action against the defecting officer. The Government had earlier toyed with the idea of getting the Delhi Police or the Central Bureau of Investigation to file the OSA case. It has now decided that the Cabinet Secretariat will file the complaint directly in the court of a Chief Metropolitan Magistrate. Top Government officials told The Indian Express that since an exhaustive probe had been conducted by the RAW and PMO, there was no need for another investigating agency to come into the picture. The final sanction for the OSA case will be given by Home Secretary Dhirendra Singh. The Government is likely to ask for the proceedings to be held in camera. Once the complaint is filed, the court may issue summons and later a warrant of arrest for Singh, who is suspected to be living with his wife in New York. Several legal experts consulted by the Government were of the view that the primary OSA case against Rabinder Singh — which is supported with surveillance records, telephone records and impounded documents — should be separated from the second case, which might implicate several other RAW officials caught on videotape helping Rabinder Singh in an ‘‘unauthorised’’ manner. Soon after the UPA Government came to power, National Security Advisor (then, the PM’s Security Advisor) MK Narayanan was asked to conduct a full-fledged inquiry into the defection episode. A copy of Narayanan’s report was given, among a few others, to the Cabinet Secretary, who had also conducted an internal inquiry. Both Narayanan and Chaturvedi recommended that a criminal case be filed.
