The probe into Karnataka's Rameshwaram cafe blast has intensified. In a statement, the National Investigation Agency clarified that they have been summoning and examining all acquaintances of the arrested and the missing accused, including their college and school friends. A BJP worker from Karnataka was reportedly questioned in connection with the case. Former Karnataka Home Minister and BJP leader Araga Jnanendra said NIA has sent him back after interrogation but his address was misused to create fake Facebook profile.
