Tamil Nadu Police Launch Spectrum to Map and Track 15,000 Sexual Offenders

The colour‑coded system centralises biometric records, phone and social‑media monitoring, and legal tools to prioritise surveillance and prosecutions of high‑risk and cyber‑enabled cases.

Overview

  • The South Police Zone formally rolled out Spectrum in late June and has mapped about 15,000 people booked in sexual‑offence cases across 10 southern districts that record roughly 1,500–2,000 such cases a year.
  • Spectrum sorts accused into eight colour categories to set monitoring levels, with red for gang rape and serial POCSO suspects, orange for repeat stalkers and harassers, blue for cyber offenders and purple for cases tied to same‑sex dating platforms.
  • Police are using Measurement Capturing Units to record fingerprints, iris and palm scans, height and high‑resolution photos and store these biometrics to help open and unsolved investigations.
  • Operational steps now prioritise red and orange cases with parole tracking, seeking convictions and bail cancellations, invoking bonds under Section 126 of the BNSS for high‑risk suspects, and active phone and social‑media monitoring for cyber cases.
  • Juvenile accused are assigned to a silver category that emphasizes parental counselling and rehabilitation, and officials say the system is meant to speed targeted patrols, focused prosecutions and preventive policing in repeat‑offence hotspots.
