The Central Bureau of Investigation (CBI) has intensified its investigation into the rape and murder of a woman doctor at RG Kar Medical College and Hospital, conducting a second round of polygraph tests on former principal Sandip Ghosh and five others due to inconsistencies in Ghosh's statements. This incident, which occurred on August 9, has sparked nationwide outrage and protests. In addition to the murder investigation, the CBI is also probing allegations of financial misconduct involving Ghosh and former medical superintendent Sanjay Vashisth, particularly concerning unauthorized tenders issued for hospital-related constructions. Recent searches were conducted at Ghosh's and Vashisth's residences, alongside 13 other locations linked to hospital management. The investigation was prompted by a complaint from a former deputy superintendent, alleging irregularities in tender processes. The CBI continues to pursue leads in both the criminal and financial aspects of the case.
