India has decided to actively pursue its case against ISI and Lashkar-e-Taiba operative David Coleman Headley for filing chargesheets against him in the 26/11 attacks case and German Bakery blast of Pune of February 13, 2010.
Both the cases are with the National Investigation Agency (NIA).
India is expecting to formally receive all evidences and documents submitted by the US authorities in the Chicago court for the trial of Tahawwur Husain Rana in the next 15 days.
According to sources, during his testimony in the US court, Headley had admitted that he had done a recee of the German Bakery as well apart from scouting targets for Mumbai attacks.
"It is a vital admission and we are considering making him a co-accused in the charge sheet. We will also press for his extradition in this case. After studying the documents received from the US, we will take a decision on seeking access to Headley. If necessary, we will send a team to the US," a government official said.
The Maharashtra Anti-Terrorism Squad (ATS) has already filed a chargesheet against seven accused in the German Bakery case.
But central intelligence agencies believe that those chargesheeting in the case had only peripheral role in the conspiracy.
Headley's testimony on the aspect of German Bakery surveillance also become important in the wake admission by al Qaeda operative Mustafa al Yazid who claimed the responsibility for the German Bakery blast in a video message.
Ilyas Kashmiri, claimed to be dead in a recent drone attack, had also sent a message to Pakistani journalist Syed Saleem Shahzad, killed recently in Pakistan, after the German Bakery blast claiming indirect responsibility of the attack.
Kashmiri had warned of more attacks in the email sent to Pakistani journalist. Now Headley's testimony makes it clear that he was close to Kashmiri.
Government sources believe that there is a need to pursue this line of investigation in the German Bakery blast. According to sources, there is little evidence to prove the involvement of Rana in the 26/11 conspiracy.
The government wants to seek access to Rana to firm up its case against Headley.
"We are trying to firm up our case against Headley. If we get access to Rana, we will try to get more information on Headley from him. Also once we receive the evidences from the US authorities, we will be able to go to the court here to pursue our case against Headley in the 26/11 and German Bakery case as well," an official said.
