Delhi Police’s claim that facial-recognition cameras flagged more than 2,000 people with criminal records at Jantar Mantar has intensified a dispute over surveillance, policing and accountability after weeks of youth-led protests.
Police sources said the technology screened people entering the protest area and identified what they described as “anti-social elements”. The figure has not been independently verified, and police have not released names, matching criteria, confidence thresholds or details of the records used to classify those identified.
The Cockroach Janta Party, which led the agitation over examination paper leaks and recruitment failures, responded by saying it would publicly identify officers accused of assaulting students. Spokesperson Ashutosh Ranka said the group would use videos, photographs and public testimony rather than facial-recognition software.
“We will identify them not through FRS but through the public,” Ranka said, alleging that officers had injured demonstrators, dragged volunteers and struck young women during police action.
The allegations against individual officers have not been established. Delhi Police said its personnel faced stone-pelting and attacks during the July 20 “Sansad Chalo” march, when protesters attempted to move from Jantar Mantar towards Parliament. Police used tear gas and lathis after barricades were breached and clashes spread into adjoining areas.
At least 130 police personnel and about 65 students were reported injured. Fifteen first information reports were registered under provisions covering obstruction of public servants, assault, conspiracy, weapons offences and damage to public property. Investigators have also said they will examine whether excessive force was used by officers.
The facial-recognition operation involved a mobile command vehicle receiving live CCTV feeds and an “Ikshana” surveillance van equipped with cameras offering a 360-degree field of view. Software inside the vehicle placed boxes around faces and compared them with images held in a police database.
A senior officer said the system was intended to alert police when it found a possible match with a known offender. There has been no official confirmation that the equipment was linked to Aadhaar, despite claims circulating on social media after screens inside the vehicle appeared to display personal details.
Students at the protest site said the cameras prompted some demonstrators to cover their faces. Several feared that being recorded at a political protest could affect applications for government employment or expose them to questioning later, even when they had not been accused of an offence.
The deployment has widened an existing legal challenge over monitoring at Jantar Mantar. A petition before the Delhi High Court alleges that round-the-clock filming, permanent surveillance infrastructure and extensive police videography violate rights to privacy, dignity, free expression and peaceful assembly.
Delhi Police maintained that photography and videography were undertaken to preserve public safety and law and order, not to snoop on protesters. The court has sought a response from the Centre. The dispute is sharpened by the absence of specific public rules governing how long footage may be retained, who may access it and how an incorrect facial match can be challenged.
The Digital Personal Data Protection Act covers the processing of personal data, but provides broad exemptions for government agencies in areas including security and public order. Civil-liberties advocates argue that live facial recognition at a protest must still meet constitutional tests of legality, necessity and proportionality.
Police are separately examining more than five terabytes of material connected to the July 20 clashes. The investigation includes CCTV footage, mobile-phone data, social-media posts, WhatsApp groups, encrypted Bitchat communications and speeches delivered after activist Sonam Wangchuk was removed from the protest site on July 18. Officers alleged that about 2,500 people were involved in violence, with 100 to 200 suspected of inciting crowds or participating in stone-pelting.
