CBI asks Bengal court to order narco analysis on ex-principal Sandip Ghosh

The CBI is contemplating conducting a narco analysis test on Sandip Ghosh, the arrested former principal of RG Kar hospital, in connection with the rape-murder of a woman doctor at the medical establishment, an officer said on Friday.

The central probe agency, during its submission in the Sealdah court on Friday, said that Ghosh has not been cooperating with the investigators.

Ghosh has already undertaken a polygraph test. During a narco analysis test, the drug sodium pentothal is injected into the body of the subject, which takes him to a hypnotic state, and his imagination is neutralised, the CBI officer said.
