According to the investigation documents, in today's investigation, former RGKR president Sandip Ghosh has claimed that on August 9, at 10:20 am, the death of the PET doctor was known, about 50 minutes later when a first year PET student came to know about the death of the PET doctor at 9:30 am, he and his colleagues of RGKR police were shown. It was known 10 minutes after calling Tala police station. The record of which is registered in the police station as GD number 542 at 10:10 am.

Let us tell you that Ghosh has been repeating the same thing repeatedly for the last 18 days as if he had done this last night, whereas before this he was questioned by Kolkata Police and then Central Investigation Bureau, he has also been polygraph tested twice.

According to Ghosh, Sumit Roy Tapdar, associate professor of respiratory medicine at RGK Hospital, called him on his mobile at 10 am. However, she reportedly did not pick up the phone as she was in the bathroom and was not staying.

Ghosh said he called Tapdar back at 10:20 am and that was the first time he came to know about the death of the Piyati doctor. He said he then called several people on the way to the hospital and called Osama of the Tala police station. However, only Omi answered his call at 10:30 am and Ghosh told him that he had already come to know about the incident. Others whom Ghosh called were Sanjay Researcher, chairman of the MS Value Welfare Department, Sudipto Roy, chairman of the patient committee, and Arunabha Chaudhari, chairman of the Chest Medicine Department. Ghosh claimed that they had taken the labourers to safety, according to the former producer, they were at the SRH hospital around 11 am.

The investigating officer wants to know that there were many people present in the hospital that day who were not related to RG Kar, but were known to Ghosh. They all reached the hospital before her parents got a call from the hospital that their daughter had committed suicide. Ghosh does not have a clear answer to this.

The investigating officer has questioned Const Ghosh on the fact that the victim doctor informed the daughter's parents about the incident and instructed the caller to look like this. Now the police is investigating this and questioning why Ghosh was not there when the police reached RG Kar Hospital. Apart from studying the call details of Ghosh, the investigators are also talking to the non-official officer of the hospital. As some more polygraphic tests can also be done.
