Even as the forensic report is awaited, a senior police official has said the Wednesday’s explosion at Malleswaram, which injured 16 persons, was not a low-intensity blast.
While initial reports said it was a pipe bomb, officials now say the device contained at least 3 kg ammonium nitrate. They suspect that it was planted in a container attached to the bike, most likely in the rear portion. Officials suspect the perpetrators to be professionals.
Among the victims, a piece of shrapnel was removed from the student Leesha’s leg and a pellet from the chest of KSRP constable Ganesh Rao.
CCTV footage
The city police say they had obtained crucial evidence from the CCTV footage, thought the quality of the footage was not up to the mark, and are trying to get a better view of possible suspects with the help of forensic analysts.
A source said: “We have questioned several persons, including witnesses, but have not detained anyone.”
Meanwhile, teams from the National Security Guard and the National Investigating Agency are reconstructing the motorbike with available pieces to ascertain where exactly the bomb was fitted. The patterns of other bomb blasts across the country are also being analysed.
Teams of experts from the central and the city Forensic Science Labs are analysing the debris to ascertain the contents of the bomb.
Joint Commissioner of Police Pronab Mohanty declined to comment on the progress.
“Investigations are on the right track and details cannot be disclosed at this juncture,” he said.
