2,873 persons with criminal records were identified between July 20 and July 26 through the system at the Jantar Mantar protest site, it was further submitted.
Of these, 92 persons are linked to more than 10 cases each.
Appearing for Delhi Police, Solicitor General Tushar Mehta told the Court that there was a “misconception” about how the system operates.
“It does not identify everybody indiscriminately. It captures a face and checks whether it matches the records maintained by the National Crime Records Bureau concerning persons with serious criminal antecedents. Those are the approximately 2,800 persons referred to earlier,” Mehta submitted.
He added that no automatic action follows after a match.
“After a possible match is generated, no action is taken automatically. There is field verification. If the face of a person with a serious criminal case appears to match the database, the police thereafter verify where that person was, what their location was and what they were doing at the protest,” he said.
