The Central Bureau of Investigation on Tuesday told a designated lower court that the investigators were yet to find evidence of gang-rape in the RG Kar Medical College Hospital rape and murder case, "though investigations are still going on."
The CBI had earlier expressed its dissatisfaction at the way the preliminary investigation was conducted by the Kolkata Police which might have led to destruction of evidence.
While seeking an extended three-day remand for arrested former Principal of RGKMCH Sandip Ghosh and the Officer in-charge of Tala Police Station Abhijeet Mondal the CBI counsel said that "till now there is no evidence of gang rape but further investigation is required."
The CBI lawyer's reply came when the designated Judge asked as to whether Ghosh and Mondal too had been involved in the rape and murder of the victim a postgraduate lady doctor.
The CBI however claimed that further investigation was required to ascertain the exact role of Mondal and Ghosh in destruction of evidence.
The Court allowed an additional three-day remand of the two accused persons.
Meanwhile, the CBI on Tuesday subjected another junior police officer, this time the Additional Officer in-charge of the Tala Police Station Pallav Biswas. The police officer was summoned to explain his role in the initial days of investigation, sources said.
