4 After the assassination of Smt. Indira Gandhi by her own security guards, it became clear that the existing security system was ill suited and it became essential to devise foolproof methods to ensure effective security. Soon after Shri Rajiv Gandhi took charge as the Prime Minister of India, and after the anti-Sikh riots were brought under control, as an ad hoc measure, a Committee of Secretaries met on 4th November, 1984, to review his security arrangements and decided that :-

Security for the PM while in Delhi would be in the exclusive charge of a special group of men under the direct and unitary control of a designated officer. A Joint Director of the IB would be entrusted direct and final responsibility for enforcing the security for the PM and the special group would report to him.

The immediate security cover for the PM while he is outside his residence whether in Delhi or elsewhere will also be provided by the members of STF.

4.1 In pursuance of the above decisions and the proposals sent by the IB, 781 posts of various ranks, including plain clothes, communication and technical staff, were sanctioned by the Government. It was decided by MHA that 499 uniformed personnel would be drawn from the CRPF and placed under the operational control of the STF.
