Pune: Forensic science lab report on nature of explosives used in Pune serial blasts is likely to come out on Friday. Unconfirmed reports on Thursday said ammonium nitrate might have been used in the blasts.
The Maharashtra ATS is also likely to release sketches of suspects on Friday. Two of the suspects will be those who bought bicycles, used in the blasts, on the day of the incident.
Apart from Dayanand Patil, who was detained and grilled on Wednesday evening, five others have been detained by the police for questioning. Patil had told the investigators that he had picked up a bag from near the India Against Corruption (IAC) venue and then later realised that he had also picked up another bag which was heavy and as he was about to examine it, it exploded. The police are yet to give Patil a clean chit in the case.
Investigations hit the first hurdle on Thursday when the police found that the CCTV cameras at two of the blast sites were not working.
Before the German Bakery blasts in February 2010, the Pune Municipal Corporation had identified 70 key locations for the installation of CCTVs. That has still not been implemented.
An RTI filed in October 2011 showed that the police had asked for 837 CCTVs from the state. However, only 79 CCTVs were installed by the Pune Municipal Corporation.
Four low-intensity bomb blasts in quick succession shook Pune on Wednesday evening injuring one person. While the first three blasts took place within a radius of one km at the Jungli Maharaj Road, the fourth blast was reported from the Garware Chowk. There was also a fifth bomb which was, however, defused near a McDonalds outlet in the city.
