The CBI must swiftly conclude its probe into the RG Kar rape and murder and ensure the arrest of all those guilty, the junior doctors demanded during a march from Swasthya Bhavan to the central agency’s office in Salt Lake on Friday.

Several of the junior doctors’ demands have been met fully or partially but they are still in the dark about their first demand — justice for their colleague and the arrest of all the culprits — said a medic who had participated in the march.

The march marked the end of the junior doctors’ sit-in protest in front of Swasthya Bhavan against the August 9 rape and murder of a 31-year-old postgraduate trainee at RG Kar Medical College and Hospital.

The junior doctors, on cease-work since August 9, have announced they would resume essential services at the government medical college hospitals from Saturday.

Scheduled to start at 3pm, the march rolled out of the sit-in site around 4.10pm. Joined by many citizens, it reached the CBI office at 6.10pm. Calcutta High Court had handed the probe over to the CBI on August 13.

The junior doctors said there would be no let-up in the pressure on the CBI for a speedy probe. If necessary, the medics will again march to the central agency’s office to remind the sleuths they are still awaiting justice.

“We want the CBI to conduct a speedy probe and arrest all the culprits at the earliest. Just because no deadline has been set for the investigation, the CBI should not treat the matter with laxity,” said Kinjal Nanda, a postgraduate trainee at RG Kar.

“We are still very far from justice for Abhaya,” he added.

Asfakulla Naiya, a postgraduate trainee in ENT at RG Kar, said: “We will keep up the pressure on the CBI. We will again march to the agency’s office if we see any laxity on its part.”

He added: “We know that the CBI has a history of failing to crack cases like the theft of Rabindranath Tagore’s Nobel medallion, and this bothers us.”

During the Supreme Court hearing of September 17, a bench headed by Chief Justice of India D.Y. Chandrachud had refused to make public the contents of the sealed-cover report submitted by the CBI on the status of the probe, lest those under scrutiny become forewarned.

The CJI had said the disclosure could “dislocate” the probe. “The status report of the CBI shows that disclosing the (details of the) investigation will jeopardise the line of investigation; and let me assure you that it is to unearth the absolute truth,” the CJI had said in court.

The junior doctors had earlier marched to the CBI office on August 23. A five-member delegation had met CBI officers seeking to learn about the progress of the probe. But the central agency’s officers had declined to provide any updates on the court-monitored investigations.

On Friday, the junior doctors did not meet any CBI officer. The main slogan from the rally was “Ar koto din somoy chai/ Jobab dao CBI (CBI, tell us how much longer you will need).”

While walking to the CBI office, the junior doctors asserted that only some of their demands had been met while they had received verbal assurances on some of the other demands.

The junior doctors had marched to Swasthya Bhavan on September 10 and had been on a sit-in outside the building since then. Their demands were: the identification and arrest of “all the culprits” and clarity on their motive; the resignation of police commissioner Vineet Goyal; disciplinary action against former RG Kar principal Sandip Ghosh; the safety of all doctors and other healthcare workers; the end of the “reign of fear” at medical colleges; and the resignation of the health secretary, director of medical education and the director of health services.

The state government has removed Goyal, the director of medical education and the director of health services, but the health secretary remains in the post. Chief secretary Manoj Pant has issued a set of directives to the health secretary to ensure security in hospitals.

“Some of our demands have been met but there are only verbal assurances on our demands on security for doctors and other healthcare workers. If we don’t seeany tangible changes to improve safety measures in hospitals, we will again start a complete cease-work,” Nanda said.
