Bangalore: The forensic report on Bangalore blast will be submitted on Saturday. Sources said the report mentions that the attack was a high-intensity blast and the explosives were packed in a steel container.
The report also mentions that ammonium nitrate and inch-wide pellets were used by the attackers to cause maximum damage but the placement of the bike at the blast site minimised the impact of the attack.
Meanwhile, the NIA on Friday questioned eight suspects in connection with the Wednesday's attack after CCTV footage showed two men parking the bike outside the BJP office. Sixteen people including 11 policemen were injured in the blast which took place outside BJP's office in Malleshwaram. Those questioned on Friday included four in Tamil Nadu, three in Bangalore and one in Kerala. They were questioned by the Bangalore Police and the NIA.
Police were also hoping for crucial leads from the CCTV footage at the location. Since the footage was grainy, it was being digitally enhanced to help the ongoing investigation. Reports said some sharp nails were also found at the blast site indicating the bomb might have been packed with shrapnel to maximise damage. No other leads have been forthcoming in the case yet. The police were reportedly also trying to prepare sketches of the culprits based on eyewitness reports.
After the explosion outside the BJP's office in Bangalore, the Ministry of Home Affairs (MHA) had issued a countrywide alert, asking all states to be extra vigilant. Meanwhile, the Karnataka government registered a case under Explosive Substance Act, Unlawful Activities (Prevention) Act, and various IPC provisions (attempt to murder). It also submitted its preliminary report on the bomb blast to the MHA.
