Two days after the blast, Delhi Police commissioner BK Gupta announced Wednesday’s blast was very much “our case”.
“The National Investigation Agency (NIA) is helping us with the investigation at the all-India level,” he told HT, adding that three Delhi Police teams, comprising more than 600 officers, had been constituted to liaise with the NIA.
He also said the Capital would witness unprecedented security till the end of the month.
Meanwhile, sources claimed the high court blast was the handiwork of a new terror module with its links to the absconding functionaries of the Indian Mujahideen (IM).
“This has to be a new module because after the Batla House episode in 2008, all the indigenous operatives of the IM had fled to foreign countries. We believe it is operating these cells from there and resurfacing through new recruits,” said a senior police officer.
He said that in each of the four cases, beginning with the Mehrauli blast in 2008 to the May 25 blast outside the Delhi High Court, not only was the chemical composition of the bombs different, but the bombs themselves had been placed in different kinds of containers.
While on May 25, a larger number of nails were found embedded in M-seal, the latest bomb was placed in a black briefcase or a backpack and only seven to eight nails were recovered from the blast site.
Meanwhile, more than 20,000 officers are conducting dummy checks in crowded markets, and questioning suspicious looking persons.
Their counterparts in traffic have been instructed to conduct checks not only on commuters’ vehicles but also the driver’s identity.
“We have asked the home affairs ministry to recommend Electronics Corporation of India Limited for the fast-track installation of CCTV cameras at all court complexes and advised mall authorities, too to get them at the earliest. Currently, 34 market places and 10 border areas are under surveillance and soon licence-plate-reading system will also be in place,” Gupta said.
