Jammu, Dec 12 (IANS): Jammu and Kashmir Chief Minister Omar Abdullah Monday asked for a thorough investigation into the militant attack on Law Minister Ali Mohammad Sagar at his home in Srinagar a day earlier that killed his bodyguard.

"The chief minister wants a comprehensive report and how it happened and what were the loopholes," said a senior official quoting Abdullah's instructions to Minister of State for Home Nasir Aslam Wani and Director General of Police Kuldeep Khoda.

Wani and Khoda will visit Srinagar to assess the situation and report to the chief minister by evening, the official who did not want to be named told IANS.

The assassination bid on Sagar took place in the congested Nawa Bazar area in downtown Srinagar late Sunday. One bodyguard was killed and three people were injured when suspected militants opende fire at Sagar's ancestral residence while he was inside.

There is also a possibility of the government issuing new do's and don'ts to ministers, legislators and top functionaries of political groups.

Abdullah has spoken to Sagar and assured all possible security to him and his family, the official said.
