The RG Kar Medical College and Hospital rape and murder case does not indicate gang-rape, the preliminary charge-sheet filed on Monday by the Central Bureau of Investigation suggests. Though other possibilities are not ruled out as there are still some missing links, “as of now Sanjoy Roy is the prime accused who perpetrated the crime,” sources said.

In the 45-page charge-sheet Roy has been quoted as telling his interrogators that he first strangulated the victim because she was resisting and then raped without realising that she had died. “If that be so then he had raped the victim when she was dead,” lawyers at Sealdah Court said.

The charge-sheet was filed on the 58th day of the rape and murder taking place inside the seminar hall of the chest medicine department of the RGKMCH. Roy was arrested a day after the body of the 31-year-old postgraduate trainee doctor was recovered at the place of crime on August 9. The incident had resulted in nationwide protests by the fraternity that are still continuing.

Roy, a civic volunteer working with the Kolkata Police, was also subjected to a polygraph test. He reportedly told the investigating officials that he had gone to the fourth floor on the fateful morning where the lady doctor was sleeping during a break.

A Bluetooth device found near the victim’s body led to the arrest of Roy who was also captured in CCTV footage while he was going to the third floor of the hospital building.

Claims made in the CBI charge-sheet notwithstanding, the general view of the doctors of the RGKMCH is that the way the victim was raped and the number of injuries she sustained could not be the handiwork of a single person.

Suspicion got stronger when the hospital authorities upon the orders of the then college Principal Sandip Ghosh started renovation in the area where the crime had taken place. Ghosh has since been arrested along with the officer in-charge of the local Tala Police Station which has jurisdiction over the area on charges of tampering of evidence.

Apart from Roy, four persons have been arrested in the RG Kar rape and murder case, on charges of tampering evidence and carrying out a corruption racket inside the Health Department.

Meanwhile, the junior doctor’s indefinite fast in demand of justice for the victim entered its second day on Monday with the senior doctors too joining them in a symbolic fast.

Apart from demanding justice for the victim, the doctors have placed a ten-point demand before the State government that includes centralised referral system for patients so as to save the harassment of shuttling between hospitals in search of beds, total CCTV coverage, adequate security deployment inside hospitals, restrooms and washrooms for the doctors, end of the “threat syndicate” perpetrated by doctors loyal to the ruling party and not least the removal of Principal Health Secretary NS Nigam from his post.

Elsewhere a team of doctors from the All India Institute of Medical Sciences on Monday conducted the postmortem of the 11-year-old girl who was on Saturday evening raped and murdered at Mahishmari village in Joynagar block of South 24 Parganas.
