<h1>ED zonal office CCTV footage collected after alleged assault by ED officials, preserved for criminal investigation and review</h1> Local police collected CCTV footage from the zonal office of the Enforcement Directorate (ED) following a criminal complaint alleging assault by ED officials during interrogation; this introduces a law-enforcement evidential preservation and review action, enabling potential use of the footage in a criminal investigation and any related prosecutions or disciplinary proceedings. The scrutiny of recordings by a team including a DSP and station in-charge operationalizes investigatory oversight and fact-finding. Deployment of CISF personnel to the ED office constitutes a security measure to protect potential evidence and premises. Allegations of possible evidence tampering were publicly asserted, which may prompt judicial scrutiny or ancillary court petitions.
