He was arrested on August 7, hours after a sessions court rejected his and another student’s anticipatory bail plea, holding that prima facie they had downloaded books written by members of banned organisation CPI (Maoist) and had raised slogans for the release of former JNU students Umar Khalid and Sharjeel Imam, behind bars since 2020 under the Unlawful Activities (Prevention) Act (UAPA).Seven others, students at the institute when the FIR was filed in 2025, were granted pre-arrest bail.“Notices have been served on the personal and TISS institute email ID of two college professors, who had sent suspicious WhatsApp messages to the accused. It is necessary to confront the accused and investigate him in the presence of the concerned professors. For this purpose, police custody of the accused is necessary,” police said in the remand plea.
