The first leads in Friday’s serial blasts have started emerging after investigators found, defused and analysed an unexploded bomb in the posh Koramangala area of the city on Saturday morning. The bomb was found metres away from the spot where a woman was killed in one of Friday’s blasts.
Investigations by the five-member team of ballistic and explosive experts from the National Bomb Data Centre, which arrived in Bangalore on Friday night, indicate that the devices were prepared and planted intelligently. The findings, which have been accessed by HT, reveal that though the bombs were of low intensity, they had been assembled from locally available substances.
“The devices are all the same,” confirmed Bangalore Police Commissioner Shankar Mahadev Bidari.
The investigators have, however, refuted earlier reports of the use of a mixture of ammonium nitrate and fuel oil, technically termed as AN/FO, based on the examination of the unexploded bomb found at Koramangala.
“We have not yet found traces of ammonium nitrate. AN/FO is a high-intensity explosive, and had it been used the casualties would have been much higher. Here, a low-intensity explosive has been used intelligently to create panic and not kill people like in Hyderabad and Jaipur,” said one of the investigators. “A decade back, cadres of the Peoples War Group were known to be using this kind of explosives in this part of the country.”
They bomb squad has also refuted any similarity between the devices used here and in Hyderabad and Jaipur.
The police probe is moving along two primary routes: the Hyderabad connection, and establishing the identities of the three people who planted the bombs.
As first reported by HT on Friday, police officials confirmed that they will be closely investigating Mohammed Muqeemudin Yasir and his brother Raziauddin Nazir, as both are suspected to have links with terrorists in Karnataka. Yasir, who was arrested on July 15, has confessed to have taken LeT operatives to Karnataka and arranged safe houses for them. Before he was arrested on January 29, Nazir is known to have recruited operatives from the state and arranged training camps in the forests around Hubli.
After the unexploded bomb was recovered, witnesses told the police they had seen a young man in a red T-shirt and denims plant something around 10.30am.
