A software engineer arrested for his links with terror group Indian Mujahideen has filed an application before a court seeking pardon in the case in return for aiding the investigators, officials said on Sunday.

The application was filed before a MCOCA court by Mansoor Peerbhoy through his lawyer Subhash Kanse on October 2.

Peerbhoy allegedly was among the main members of the media wing of the terror group and was responsible for sending threatening emails prior to the Ahmedabad serial blasts on July 26 and Delhi blasts on September 13 using wireless internet connections in Navi Mumbai and Mumbai respectively.

Peerbhoy has said in his application that he would be willing to aid investigating agencies and has asked what pardon the state can grant him, court sources said.

Joint Commissioner of Police (Crime) Rakesh Maria said an application had been filed by Peerbhoy.

"The application has been filed before the MCOCA court by his lawyer and we have been asked to file our say by November 4," Maria said.
