Palghar police in Maharashtra has set up a measurement collection unit (MCU) on the directives of National Crime Records Bureau (NCRB) that has asked for the establishment of such units at all district levels nationwide, an official said on Friday.

The MCU, which has come up under the Criminal Procedure (Identification) Act 2022, will collect, store and analyse physical and biological data of arrested individuals involved in criminal cases, he said.
This includes the collection of fingerprints, retina scans, body measurements, identification marks or wounds, and photographs, including images of private parts as permitted under law for forensic purposes, the official added.

"Through this system, all districts in the state and all prison administrations have now been interconnected. This modernized unit replaces the outdated Identification of Prisoners Act, 1920, which limited data collection to only fingerprints and photographs," a Palghar police release said.
