An under-trial prisoner in the 2008 Delhi serial blasts case on Wednesday accused the National Investigation Agency of “approaching” him in Tihar Central Jail without taking the permission of the Tis Hazari sessions court where the case is progressing.

Additional Sessions Judge Santosh Snehi Mann, after receiving the complaint of alleged Indian Mujahideen member Shahzad, directed the Tihar Jail superintendent to file a report on the matter by September 28.

“An application is moved on behalf of Shahzad that officials of the NIA are approaching him in the jail [Tihar] without permission of this court. A report be called from the Jail Superintendent on this application for the date fixed,” Ms. Mann said in her order.

The NIA is presently probing the blast outside the Delhi High Court on September 7. On Wednesday, 19 witnesses were examined, including six doctors, and victims who had sustained injuries, besides those who lost their family in the serial blasts. Last week, the court had ordered the expediting of the trial by listing the case to be heard on all Wednesdays and decided to examine at least 15 witnesses on each hearing date.
