The National Investigation Agency teams stationed in different parts of the country have been alerted to pursue leads, obtained from mobile phone records, suggesting that those arrested in the Bardhaman blast case had links in several States.
“Phone records reveal that they had contacts in almost all the major megacities, also in South India. We will have to verify the antecedents of each and every contact. Six of the Assam-based suspects who were in touch with the two men killed in the blast have already been arrested,” said an official.
