Pulwama attack: While much of the jerrycan has been destroyed, this material, investigators said, broke away and survived the blast. From these remains, investigators estimate that the can was not more than 20-25 litres in size and so could not have held more than 30 kg of RDX, the explosive suspected to have been used.
The NIA had taken over the case in 2009 and filed a chargesheet in 2010. According to the chargesheet, on March 3, 2006, local police received phone information from the media that two bombs had been planted at the KSRTC bus stop and Mofussil bus stand in Kozhikode city.
NIA said Mohammed Ashar, a resident of Thalassery in Kannur district of Kerala, had been absconding and was chargesheeted by the National Investigation Agency in 2010. He was arrested on Thursday from the Indira Gandhi International (IGI) Airport, it said.
The 29-year-old Islamic preacher, who was arrested by NIA last week from his home in Jaffrabad, Delhi, told interrogators that he had been hurt by events such as the Babri Masjid demolition and believed that Muslims were discriminated against in the country.
Led by an Islamic preacher, the self-appointed group was planning to carry out a series of blasts across the country and several important personalities including politicians were on the target list, the probe agency said.
The agency said that as part of the conspiracy, 14 accused from Kasaragod district had left India or their workplaces in Middle-East Asia and travelled to Afghanistan or Syria, where they joined the ISIS (Daish).
Agencies have been conducting surveillance on internet communication for several years now, particularly in matters related to terrorism. The 2013 Bodh Gaya blasts case was cracked in great measure with crucial online communication intercepts.
