RAWALPINDI, Aug 1: A joint investigating team, comprising police and intelligence officials, is taking help from the National Database and Registration Authority (Nadra) to identify the person who had blown himself in a terrorist attack on Finance Minister Shaukat Aziz in Attock on Friday , a source told Dawn on Sunday.

The bomber's body parts collected from the scene of attack have already been shifted to CMH, Rawalpindi, where they are being stitched to recognise him, the source said.

He said investigators had also taken finger prints of the bomber from his body parts and were trying to take help from the Nadra for his identification. Sketches of the bomber have also been drawn, he further said.

When Deputy Inspector General of Police, Rawalpindi, Iftikhar Ahmed, who is leading the investigation, was contacted, he said no group had so far claimed responsibility for the attack.

A source close to the police claimed that an unexploded Dara- made plastic hand-grenade had also been recovered from the scene. But the DIG denied that police had found any explosive device.

The team is also working on whether a remote-control was used to blow the bomber. Meanwhile, the number of law-enforcement agency officials on duty has been increased at the minister's colony and at all busy crossroads in Islamabad.
