Nearly 1,000 people identified after the 20 July Parliament march had previous criminal records, according to a Delhi Police report.
According to The Times of India, police identified 989 people with criminal antecedents after examining 2,873 individuals linked to the march.
Police said they used facial recognition technology, CCTV footage, and videos recorded by officers and members of the public to identify those present.
Among the 989 people identified:
101 had previously been accused in murder cases.
284 had been booked in dacoity or robbery cases.
62 had been booked for attempted murder.
229 had cases under the Arms Act.
61 had been booked in rape cases.
Six had been booked under the Protection of Children from Sexual Offences (POCSO) Act.
The figures refer to previous accusations or cases in which people had been booked. They are not convictions.
Meanwhile, the Centre told the Supreme Court that it did not believe students themselves had engaged in violence during the protests.
According to Hindustan Times, the government said "anti-social elements" may have infiltrated the demonstrations.
The Supreme Court later ordered the release of detained protesters who were under 18 and had no criminal record.
The order excluded those with criminal antecedents or those identified as "anti-social elements".
The court also directed an independent probe into both the protest violence and allegations of police excesses.
It further ordered authorities to preserve CCTV footage, drone recordings and body-camera footage as part of the investigation.
The Delhi Police report and the Supreme Court's directions are part of the ongoing legal examination into the events surrounding the 20 July Parliament march.
