The Central Bureau of Investigation (CBI) summoned 11 Kolkata police officers for questioning on Monday and Tuesday, as part of its ongoing investigation into the alleged criminal conspiracy and tampering of evidence surrounding the rape and murder of a doctor at RG Kar Medical College and Hospital.

On Saturday, the victim’s parents lodged a formal complaint with CBI Director Praveen Sood, expressing their dissatisfaction with the allegedly slow-paced and ineffective probe.

The summoned officers include sub-inspectors, assistant sub-inspectors, and constables from West Bengal’s Tala police station, who were on duty at the hospital campus police outpost on the day of the incident.

The victim, an on-duty female medic, was raped and murdered at the state-run hospital on August 9 last year, sparking nationwide outrage, particularly within the medical community.

On January 20, a Sealdah court sentenced civic volunteer Sanjoy Roy, the lone convict in the rape and murder case, to life imprisonment. The court said that the crime, while heinous, did not meet the criteria for the “rarest of the rare” category, thus imposing a life sentence rather than the death penalty. The court convicted Roy under sections 64, 66, and 103/1 of the Bharatiya Nyaya Sanhita (BNS).

Furthermore, on February 25, the CBI submitted a status report to a court in Sealdah regarding the alleged tampering of evidence in the case. The CBI stated that the investigation is still ongoing and that a supplementary chargesheet will be filed in the near future.
