Could Pune blast be Headley's brainchild?

New Delhi, Feb 14 (ANI): Was Saturday's Pune blast a brainchild of arrested Lashkar operative David Headley? The question is haunting North Block here.

According to sources, Saturday's blast is being seen as the first of its kind planned by Headley.

On Saturday, a bomb blast ripped through the Pune's popular German Bakery, close to the Osho Ashram and diagonally across from the Jewish Chabad House, recced by Headley, killing at least nine people.

After a high level meeting, sources felt that sleeper cells remained active in most parts of the country even after Headley's arrest.

On 12, October 2009, the Union Home Ministry had informed the Maharashtra Government about the locations surveyed by Headley.

They did not even rule out hand of the Indian Mujahideen (IM) in the blast.

Meanwhile, the Centre has issued a fresh advisory to Delhi, Kanpur and Indore where IM members are suspected to be active.

Security personnel have reportedly started questioning Batla House encounter suspect Shahzad Ahmad to find out if he had any information about the Pune attack. (ANI)
