Abstract
This study examines the historical evolution of Artificial Intelligence in criminal investigations in India, tracing the transition from manual policing to data-driven and AI-enabled systems. It highlights key developments such as NCRB, CCTNS, ICJS, predictive policing, and AI surveillance technologies, while analysing the legal and ethical frameworks governing their use. The paper argues that technological advancement must be balanced with privacy, accountability, and constitutional safeguards to ensure fair and transparent criminal justice.
