The review was carried out after central security agencies received an alarming intelligence input that militants had carried out a reccee to plan a suicide attack on Mukherjee, who was earlier the Defence Minister.
Intelligence sources said certain Pakistan and Bangladesh based militant outfits like Lashkar-e-Toiba and Jaish-e- Mohammad were named as groups which were planning to carry out the attack on Mukherjee, who already has high Z-Plus category security cover.
The Home Ministry has also directed Delhi and West Bengal police forces to take adequate measures and ensure fool-proof security for the Union Minister, the sources said. Besides holding the key portfolio of External Affairs, Mukherjee also heads the UPA-Left committee on Indo-US civil nuclear deal and various Group of Ministers (GoM) constituted on important issues. A circular has been issued to West Bengal police as the minister frequently visits his home in the state.
