New Delhi, Sep 22 (IANS): The National Investigation Agency (NIA) Thursday got till Oct 5 the custody of a man suspected to have a hand in the Sep 7 Delhi blast, a day after he was brought to the capital from Jammu and Kashmir.

Abid Hussain, who along with Shariq Ahmed and Amir Abbas Dev, was brought here by the NIA team Wednesday on three days' transit remand from Kashmir, was presented in the court of Additional Sessions Judge H.S. Sharma.

Hussain was brought to the Patiala House district court complex around 8.30 a.m. and presented before the judge for the in-camera proceedings.

"The proceedings went on for around 45 minutes. During the proceedings, the judge asked Hussain about his age, to which he replied that he was a major, not minor. His certificate did not carry his date of birth," said a court staffer.

"The NIA sought 15 days' remand to unearth the conspiracy in the Sep 7 blast," said the staffer. The court granted the NIA his custody till Oct 5.

Another suspect, Amir Abbas Dev, was sent to judicial custody for a day. "He did not have a lawyer for defence. He has been sent to Tihar Jail. He will be presented before the court Friday," said Amit Sharma, NIA counsel.

Shariq Ahmed, the third man arrested and brought from Jammu and Kashmir, is expected to be presented in court later.

The blast at the Delhi High Court killed 15 people.

In Jammu and Kashmir, Dev, arrested Sep 16, was remanded in police custody for seven days, while Ahmed and Hussain were arrested Sep 13 and sent to police custody for 10 days.

The accused have been booked under Sections 120-B (criminal conspiracy), 153-A (promoting enmity between different groups on grounds of religion, race or language and doing acts prejudicial to maintenance of harmony) and 134-A (attack on government servant on duty) of the Indian Penal Code.

The NIA has announced a reward of Rs.10 lakh for anybody giving information about those who hatched plans for and engineered the blast.
