Face Scans Complete, Delhi Police Zero In on Protesters With Criminal Records

Facial Recognition Used in Protest Investigation

Delhi Police has intensified its investigation into the violence that broke out during the July 20 "Sansad Chalo" protest by using its Facial Recognition System (FRS) to identify people present at the demonstration. Officials said facial scans of 2,873 individuals captured through CCTV cameras and other surveillance footage have been analysed as part of the probe. The technology was used to match faces with existing police databases to identify individuals with previous criminal records and verify whether they were involved in the unrest.

Nearly 1,000 People Flagged

According to police sources, 989 individuals identified through facial recognition were found to have prior criminal records. These include people previously booked in cases related to murder, attempted murder, robbery, kidnapping, assault and other serious offences. Officials clarified that having a criminal record does not automatically mean a person was involved in violence during the protest. Investigators are now examining CCTV footage, eyewitness accounts and other evidence to determine each individual's role before initiating further legal action.

Multi-Layered Investigation Underway

Police are relying on multiple sources of evidence, including CCTV footage, drone recordings, mobile phone videos, social media posts and technical surveillance, to reconstruct the sequence of events. Authorities said every identified individual will be cross-verified with visual and forensic evidence to ensure that only those directly linked to acts of violence or vandalism face prosecution. Several FIRs have already been registered, and additional arrests are expected as the investigation progresses. Officials also said the probe is focused on identifying those who allegedly attacked security personnel, damaged public property or instigated violence.

Privacy Concerns Surface

The use of facial recognition technology has reignited concerns among privacy advocates and civil rights groups, who argue that large-scale surveillance at public demonstrations could infringe on citizens' rights if not backed by strong legal safeguards. They have called for greater transparency regarding how facial recognition data is collected, stored and used. Delhi Police, however, defended the use of the technology, saying it is a legitimate investigative tool aimed at identifying offenders and ensuring accountability while maintaining public order.

The investigation remains ongoing, with police continuing to analyse digital evidence and question suspects. Authorities have said the final action will depend on individual involvement established through evidence rather than facial recognition matches alone.
