Jammu/New Delhi: The NIA on Wednesday brought all the three accused - arrested in connection with sending an email claiming responsibility for the High Court blast – to Delhi where they are likely to be extensively questioned.

The three - Shariq Ahmed, Abid Hussain and Amir Abbas Dev - were brought to the national capial by a NIA team led by DIG Mukesh Singh and are likely to be produced before a magistrate for further remand.

The team was accompanied by Deputy Inspector General of Police (Doda) Muneesh Singh of Jammu and Kashmir Police who will be assisting the NIA in its probe, official sources said.

While Dev, shown arrested by NIA on September 16, was remanded to police custody on seven days, the other two - Shariq and Hussain - were arrested on September 13 and have been sent to police custody for 10 days.

The three were taken on a transit remand after which they would be produced before a magistrate in Delhi during which NIA would seek the court's permission for carrying out scientific tests on them and questioning them.

The probe had hit a road block when Dev retracted his earlier statement in which he had admitted to his role in the terror attack.

Dev has withdrawn his earlier "detailed statement" about his role in the blast, sources said, adding police was facing difficulty in corroborating his earlier statement as there were many loopholes.
