Still looking for clues to crack last night's serial blasts here that left one injured, Pune police today said no arrest or detention has been made in connection with the incident and that it was probing if it was the handiwork of a terror outfit.
"There has been no arrest or detention so far. We arecollecting scientific evidence in the ongoing investigations", JointCommissioner of police Sanjiv Singhal told reporters.
Amid reports that Indian Mujahideen, which was behind 2010German Bakery blast here that claimed 17 lives, could have triggered the serialblasts, the officer refused to confirm whether the home-grown terror outfit wasinvolved in the quadruple explosions.
"We will be able to tell only after investigations arecomplete. It will not be proper to make a comment at this stage," Singhalsaid when asked whether the blasts carried the stamp of a terrorist network.
Maharashtra Home Minister R R Patil, who visited the fourblast sites earlier in the day also said investigating agencies were probingall angles to determine whether any terror outfit was behind the low-intensityblasts.
"Whether it was a terrorist act or not will bedetermined only after proper investigations are carried out by Maharashtra ATS,city crime branch and central agencies," he said.
"All angles are being probed and it will not be properto comment at this stage," he said when asked if there could be a"saffron terror" angle to the blasts.
He said few days after the murder of terror suspect QateelSiddique in Yerwada prison, Pune police had got a letter in Marathi whichthreatened that the murder would be avenged. "This angle is beingprobed," Patil said.
Suspected Indian Mujahideen operative Mohammad QateelSiddiqui was lodged in Yerwada Central Jail for his alleged role in in theGerman Bakery blast and the Bangalore terror attacks. He was found murdered inhis prison cell in June this year after a brawl with some fellow inmates.
Patil said there were no inputs from central agencies aboutthe blasts.
Singhal said the sole person injured in the blast near BalGandharva theatre, the 33-year-old Dayanand Patil was being"interrogated". His wife Satyakala and some bicycle shop owners inthe city's Kasaba peth area were also questioned as part of the investigations.
"A box like object was used to plant the bombs whichwere triggered with detonators, 9 volt battery cells and timer," Singhalsaid, adding that a white substance too had been found and sent to forensiclabs for investigations and reports were awaited. There were unconfirmedreports that ammonium nitrate was used to trigger the blasts.
Investigators trying to string together bits of evidencewere reported to have hit a hurdle as some CCTV cameras at the explosion siteswere found to be non-functional.
The CCTV cameras installed at Dena Bank, McDonald's and BalGandharva traffic square, near where the explosions occurred, have not yieldedany clue so far and some of them were non-functional.
Sources said the Maharashtra ATS, city Crime Branch and theNIA are looking for clues from the two bicycles as two of the four coordinatedblasts occurred in their front carriers.
Explosives were strapped on these bicycles which appearnewly purchased and investigators are trying to locate the shop from wherethese were bought in order to nail the perpetrators.
Police have registered an offence against "unknownpersons" under sections 307 (attempt to murder), 427 (mischief causingdamage), 120 B (criminal conspiracy) and relevant sections of UnlawfulActivities Prevention Act and Explosive Substances Act.
