KOLKATA: Calcutta HC on Tuesday directed CBI to produce all documents, audio recordings, videos and photographs related to the investigation of the RG Kar rape-murder case and said the court would examine on Thursday whether there was any scope for further probe in the matter. Refusing immediate permission to the victim's parents to visit the crime spot, a special bench comprising Justices Shampa Sarkar and Tirthankar Ghosh asked their counsel to first satisfy HC on the legal grounds for such a request. The special bench was assigned the matter by Chief Justice Sujoy Paul after three HC benches recused themselves from hearing the case. Justice Sarkar cautioned all parties against making public comments on the matter. Senior advocate Jayanta Narayan Chatterjee said the seminar hall of RG Kar Medical College and Hospital was not the only scene of the crime, adding other areas, including the seventh-floor OT and chamber of then-principal Sandip Ghosh, had remained open since the first day, and despite repeated requests to CBI to examine and seal those areas, no action had been taken.
