The Delhi Patiala House Court on 27 March 2026 granted the NIA an additional 45 days to complete its investigation into the Red Fort blast of 10 November 2025 . The extension follows recent arrests of two suspects, Zamir Ahmed Ahangar and Tufail Ahmad Bhat , and is the second time the court has allowed a time‑extension beyond the statutory 90‑day period. Key Developments Special Judge Prashant Sharma approved a second 45‑day extension, permissible up to 180 days under the law. The NIA’s plea cited fresh leads emerging from the arrests of Ahangar and Bhat. Earlier, on 13 February 2026 , the court had already granted a first 45‑day extension. The investigation points to a terror module led by a group of doctors who spent nearly a year searching for a suicide bomber. Umar‑un‑Nabi is identified as the main accused, allegedly driving the explosive‑laden Hyundai i20 that detonated. Important Facts Casualties: 14 dead and several injured. Arrests: Around 11 individuals detained for facilitating the attack, providing logistics, harbouring suspects, and attempting evidence destruction. Legal framework: The Criminal Procedure Code allows investigation extensions up to 180 days for terror cases. UPSC Relevance Understanding the procedural aspects of terror investigations is crucial for Special Judge courts, the role of the NIA , and the legal limits on investigation periods. The case also highlights the intersection of heritage security (Red Fort) and counter‑terrorism policy, a recurring theme in GS1 (History) and GS2 (Polity) papers. Way Forward Complete forensic and digital analysis within the extended timeframe to identify any remaining conspirators. Strengthen security protocols at heritage sites, integrating intelligence inputs with on‑ground vigilance. Review the efficacy of the 180‑day extension provision to balance investigative depth with judicial efficiency.
