CBI Granted Permission for Polygraph Tests in Doctor Murder Case

A special court in Kolkata has granted the Central Bureau of Investigation (CBI) permission to conduct a polygraph test on Dr. Sandip Ghosh, the former principal of R.G. Kar Medical College, as well as four other medical professionals involved in the case of a tragic murder.

The court’s approval extends to four colleagues of the victim, a 31-year-old trainee doctor, who were present on the night of the crime. The CBI intends to carry out these tests to assess the credibility of the statements given by the individuals.

Previously, on August 19, the CBI received authorization to conduct a polygraph test on Sanjoy Roy, the main suspect in the case. This development led the Calcutta High Court to postpone a subsequent hearing until August 29.

Sanjoy Roy, a 33-year-old civic volunteer, is accused of assaulting and murdering the young doctor in the early hours of August 9. He was arrested the following day after the doctor’s body was discovered in the seminar hall of the hospital.

In light of the investigation, Dr. Ghosh’s transfer to Calcutta National Medical College was revoked, amidst widespread protests regarding the circumstances of the incident. The former principal resigned from his position shortly after the body was found.

A polygraph test, commonly referred to as a lie detector test, serves to measure physiological responses while an individual answers questions. According to the American Psychological Association, these tests do not directly measure honesty but are intended to infer the likelihood of a person’s involvement in a crime.

The results of the polygraph tests could provide clarity regarding inconsistencies in the statements made by the suspects. Investigators will assess physiological reactions during questioning to determine any indications of deception.
