The polygraph examination of Assistant Sub-Inspector Anup Dutta commenced at the Central Bureau of Investigation (CBI) office on Wednesday, as confirmed by CBI sources to ANI. This development follows the CBI’s request for judicial approval from a Kolkata court to administer the test on Dutta, who is reportedly linked to Sanjay Roy, key accused in the rape-murder case of trainee doctor at RG Kar Medical College and Hospital. 

The probe agency is examining whether Assistant Sub-Inspector Anup Dutta may have assisted Sanjay Roy in concealing the crime. Reports suggest that Dutta is suspected of providing various favors to Roy. The central probe agency is investigating if Roy informed Dutta about the crime and if Dutta offered any assistance in covering it up, reported PTI.
