The Central Bureau of Investigation (CBI) is intensively investigating the alleged rape and murder of a trainee doctor at RG Kar Medical College and Hospital, which occurred on August 9, with a focus on specific rooms near the crime scene, including one possibly linked to the incident. Protests have erupted following the incident, prompting calls from West Bengal Minister Chandrima Bhattacharya for a strong prosecution to ensure justice. The CBI has conducted multiple rounds of polygraph tests on key individuals, including former principal Sandip Ghosh, whose membership in the Indian Medical Association has been suspended amid the investigation. Additionally, the CBI is probing alleged financial corruption at the hospital, including improper biomedical waste disposal, which raises further concerns about institutional integrity. The case has garnered national outrage, leading to its transfer from local police to the CBI by a Calcutta High Court order. The investigation continues as the agency seeks to uncover more evidence related to both the crime and potential corruption at the hospital.
