Drawing blank so far over its probe in Pune bombing, Maharashtra’s Anti-Terrorism Squad (ATS) is now banking on the forensic results of the DNA samples collected from the site of the explosion at German Bakery here.
The forensic experts have lifted nearly 70 DNA samples from the scene of explosion and were trying to link them with those who had either been killed or were injured, official sources said.
A senior official said that they want to rule out all possibilities before moving on in the investigations and hinted that a profiling of all the DNA samples collected would be conducted.
The explosion had not left any clues about the mode of detonations and hints were being made that either a timer had been used or mobile phones were being used for detonation of the bomb on February 13 which comprised 99 per cent of deadly RDX and one percent Ammonium Nitrate, sources in the investigating agency said.
The ATS along with security agencies were examining almost all the calls in and around the German Bakery that was picked at the time of the blast.
The investigators were also baffled by the promptness of the local police which had washed the blast site with water thinking that it was a gas cylinder blast.
The ATS has drawn blank so far from the interrogation report of a few jailed Indian Mujahideen (IM) terrorists to get some leads on who could be behind the Pune terror attack which killed 15 people including two foreigners.
Among those whose interrogation report was examined were Saddiq Sheikh, believed to be one of the founders of IM, and Mansoor Peerbhoy, sources said on Sunday.
The IM is stated to be an amalgam of former SIMI cadres and operatives of the Pakistan-based terror group Lashker-e-Taiba (LeT).
Sheikh and Peerbhoy had specially recruited a Pune resident Mohsin Chaudhury into the IM, the sources said, adding, he has been on the run.
Police believe that Chaudhury had not left the country. He had emerged as a key suspect in the Delhi and Ahmedabad blasts in 2008.
The authorities in the jail, where the IM men have been lodged, were also contacted by the probe team to know about the movement of visitors to these terror suspects lately, the sources said.
Meanwhile, two more injured died rising the toll in the bakery blast to 15.
The deceased, 23-year-old Rajeev Agarwal, a student of Symbiosis, and 24-year-old Vikas Tulsiyani from D Y Patil college, hailed from Kolkata and Delhi respectively.
