The police on Friday informed the special MCOCA court that it would file the chargesheet after the 150-day-period and that the entire chargesheet, which would run into over 1,000 pages, will be handed over to the accused in court. It will have statements of over 100 witnesses detailing the entire conspiracy, they said.

The Crime Branch unearthed the group last year after monitoring members’ movements, raiding several places and using inputs from other states.

Among the arrested is Mohammed Mansoor Peerbhoy, a software professional from Pune, who is said to be the head of the media cell of the group that used to send e-mails to media houses by hacking into unsecured Wi-Fi accounts and claiming responsibility for the blasts.

Special Public Prosecutor Kalpana Chavhan said: “The police had taken a 60-day extension to file the chargesheet as investigations are still on and a few arrests were made as recently as in December 2008.”

The Mumbai police had initially arrested five men, Afzal Mutalib Usmani, Mohd Sadiq Shaikh, Mohd Aarif Shaikh, Ahmed Zakir Shaikh and Shaikh Mohd Ansari. Sadiq is believed to be the founder-member of the group along with Atif, who was killed by the Delhi Police in September last year.

Among the 21 accused, over 7 have given a confessional statement. Mansoor Peerbhoy has moved an application to turn approver, which the police are yet to accept.
