Amir Abbas Dev was remanded on Friday by a Delhi court to National Investigation Agency, NIA custody for 15 days. NIA will interrogate Dev to unearth his suspected role in the September 7 the Delhi High Court blast that killed15 people and injured over 70 others.

Special NIA Judge H S Sharma passed the order in an in-camera proceeding, which was attended only by the accused defence counsel Ravi Kazi, besides the NIA investigators.

The court turned down Kazi's opposition to plea by NIA which had produced him before the court yesterday after bringing him from Kisthwar in Jammu and Kashmir, where he was arrested.

Dev's co-accused Abid Hussain has already been remanded to NIA custody till October 5.

Hussain and Dev were brought to Delhi the day before yesterday following their arrest at Kishtwar. They had allegedly sent emails to media houses claiming responsibility for the blast on behalf of banned terror outfit Harkat ul-Jihad al-Islami.
