The charge sheet says his DNA had been found on the victim and “the short hair found from the SoC has matched with accused Sanjay Roy”.

The charge sheet says that “during investigation conducted so far, involvement of accused Sanjay Roy has been clearly established in the commission of offences punishable under sections 64, 66, 103(1) of BNS, 2023”.

It adds: “After completion of further investigation, supplementary Final Report will be filed.”
