Delhi Police Commissioner Rakesh Asthana on Saturday said a scientist, Bharat Bhushan, has been arrested yesterday for the low-intensity blast in a Rohini court on December 9.
The Commissioner said as per initial assessment, it was suggested that the possible cause of the blast was due to a battery leakage or malfunction in a laptop. “This probe was important because this blast occurred months after the Rohini shootout,” he said.
Prima facie, it appeared it was an Improvised Explosive Device (IED) blast and the investigation was transferred to Special Cell Northern Unit under a team headed by DCP Special Cell Rajeev Ranjan, the Commissioner said.
Asthana told the media how the case was cracked. The police did a dump data analysis of telephonic data of the area and analyzed the cause list and from there, we examined the litigants, lawyers and anyone who entered the said courtroom, he said.
The initial examination of the site was carried out by NSG, which led us to a conclusion that the ingredients of this IED was something that could be bought in a local market, he said.
“It was a remote triggered IED. The remote was the one used in anti-theft system of the car. It was only the detonator that had blasted, the explosive had not blasted,” Commissioner Asthana said.
After telephonic data, the cars coming into the court complex were looked at. Some 1000 cars were identified during the probe and their owners were examined, he said.
Similarly, suspicion raising footage on CCTV cameras in and outside the court led the police to look into other cameras in the area.
Anti-theft system dealers were probed who led the police to where the bag was bought. “It’s whereabouts led us to the suspects. It was a big clue.”
The bag was found to be manufactured by a Mumbai company and the police analyzed the files found in the bag.
The trail of clues led to Bhushan, according to the Delhi Police chief, who had a legal battle with an advocate and which led him to carry out this blast.
Upon searching Bhushan’s residence, the police found various incriminating evidence linking him to the blast. He had worn a black and white lawyers’ garb on the day of the blast, said Asthana. To deceive people, he had used different routes to enter and exit the court every time, the Commissioner said
