Police in Rajasthan and Delhi have become the first in the country to record, store and analyse biometric data such as the fingerprints, and retina and iris scans of all those whom they arrest, as well as some others accused of a crime.
Due to the limitations of forensic capabilities, the collection of DNA, likely drawn from blood samples, is yet to be rolled out, police officials said.
These biometric samples are being collected since March this year in compliance with the Criminal Procedure Identification Act (CrPI), which was passed by Parliament in 2022 and has now come into effect on a pilot basis in Delhi and Rajasthan after three years.
DNA guidelines being developed
The Act enables the police and Central investigating agencies to collect, store and analyse physical and biological samples, including the fingerprints, and scans of the retina and iris of all arrestees.
