Doctor rape-murder: CBI may conduct polygraph test on RG Kar ex-principal

CBI officers may conduct a polygraph test on Sandip Ghosh, the former principal of RG Kar Medical College and Hospital, where a woman doctor was allegedly raped and murdered earlier this month.

Ghosh, who resigned two days after her body was found in a seminar hall of the medical facility on August 9, has already appeared before sleuths of the central probe agency for questioning several times.

"We want to further verify Ghosh's answers, as there have been discrepancies in some of the replies to our questions. Therefore, we are mulling over the option to conduct a polygraph test on him," an official told PTI.

Ghosh was on Tuesday, too, grilled by investigators, as part of its probe into the rape-murder of the postgraduate trainee.

CBI officers have put forth various questions to Ghosh in the last few days, including specifying his role after getting the news of the doctor's death, who he had contacted thereafter and why he allegedly made the parents wait for nearly three hours befo
