A file photo of Republic TV anchor Arnab Goswami. | PTI The Maharashtra unit of the Congress on Tuesday demanded the arrest of Republic TV Editor-in-Chief Arnab Goswami, claiming that his purported WhatsApp conversation about prior knowledge of the 2019 Balakot airstrikes amounts to treason, reported The Hindu. In a purported WhatsApp chat on February 23 – three days before the strike – Goswami told Broadcast Audience Research Council’s former Chief Executive Officer Partho Dasgupta that it would be “bigger than a normal strike”. “How did Goswami get the information about the military action three days before the event, on February 23, 2020?,” Congress General Secretary Sachin Sawant told the newspaper on Wednesday. “He [Goswami] himself has said that the person who gave him this information is a big person in the Modi government. All of this needs to be investigated. The way Arnab Goswami acted amounts to violation of the Official Secrets Act, 1923.”
