The Criminal Investigation Department (CID) submitted the charge sheets of two cases filed with Sabujbagh Police Station to the Court of Chief Metropolitan Magistrate, Dhaka.

The first case was filed under the Arms Act and the other one under the Explosive Substances Act.

Other accused are AHM Shamim, 23, Zakaria alias Jewel, 21, Nur Azam Siddique alias Yeasir, 27, Belal Hossain alias Tamim, 21, Aleya Ferdous, 27, and Akramul Islam, 23.

All of them except Ataur were arrested earlier and gave confessional statements to magistrates on different dates.

In the charge sheets, the investigation officers (IOs) said the main objective behind the blasts was to establish Islamic law in the country.

They also prayed for issuing arrest warrant and attachment of movable property against Ataur.

Earlier on September 8, Rapid Action Battalion (Rab) arrested five of the accused, including the woman, at a house in East Basabo.

Ataur rented the house four to five months ago using pseudonym Hassan alias Sunny and coordinated the countrywide serial blasts. The law enforcers believe he narrowly escaped arrest.

The Rab also seized firearms, 60 CDs containing militant training manuals, 700 capacitors alike to those used in the August 17 blasts, 92 books and four audiocassettes on jihad, one computer, two printers and 10 floppy disks from the house.

Intelligence officials said Ataur used to carry out all the subversive activities from the six-storey house on Patwari Lane in East Basabo.

Other seized items include one electric blower, 17 masks, three receipt books for raising funds for madrasa, three diaries, nine books of district maps, one motorcycle and Tk 2 lakh in cash.
