Even as confusion looms large over the death of Shahid Bilal, India's most wanted terrorist, a close aide of his has revealed that Bilal along with Abu Hamza had planned the attack on the Indian Institute of Science.

A narco analysis test conducted on Abdul Sattar, a resident of Hyderabad now in custody of the cops, revealed that Hamza is a Jaish-e-Mohammed operative and he had jointly planned the IISC attack along with Bilal.

On Sunday an alleged militant by the name Sabahuddin was picked up at Lucknow in Uttar Pradesh. According to the interrogation conducted on Nasir, the militant arrested in Karnataka, it was revealed that Sabahuddin had assisted Abu Hamza in the IISC attack.

Over there he read Bilal's diary which had specifically mentioned the plot regarding the IISC attack.

Sattar also said that apart from this, Bilal had also planned to attack some software companies in Bangalore.

Among the targets mentioned in Bilal's list were the city police commissioner's office, software companies and a flyover.

The Hyderabad police now have a common person to chase along with the Bangalore police.
