The Centre had written to the Jammu and Kashmir government in June 2005 to enhance the security level of state Communist Party of India-Marxist leader Mohammed Yusuf Tarigami following heightened threat perception from militant groups, sources said.
Immediately after the attack, the Centre asertained how the militants managed to sneak into his residence in the highly-guarded zone of Srinagar's Tulsi Bagh, which houses legislators and some ministers of Congress-People's Democratic Party alliance government.
It is understood that CPI-M general secretary Prakash Karat also spoke to Union Home Minister Shivraj Patil and voiced serious concern over the security cover for Tarigami and other MLAs and CPI-M office bearers.
The state government had been asked to provide Z-plus security cover to the CPI-M leader as he was on the hit list of militant outfits especially Hizbul Mujahideen, many of whom had surrendered en masse in late 90s at the instance of Tarigami.
