A large number of doctors in Kolkata on Monday took out a procession and formed a human chain to protest against the rape and murder of their colleague in state-run RG Kar Medical College and Hospital, an incident that sparked a nationwide socio-political firestorm.

Meanwhile, two senior Kolkata-based doctors appeared before the police in connection with the posts they shared on social media on the doctor's rape and murder case.

They were accused of revealing the RG Kar rape-murder victim's identity on social media.

After appearing before the police, senior physician Subarna Goswami said: "The discussion took place in a cordial atmosphere. The summon sent to us has been shut down. Police told us that they want to restore peace in Kolkata and sought help."

He said: "We told the police there was no need to summon us."

Speaking to the media after appearing before the police, Kunal Sarkar said: "We are saddened by the death of our colleague. We are angry and want a proper investigation into the case. We do not want to aggravate the situation."

He said: "We did not reveal the identity of the victim."

At the starting of the march from Calcutta Medical College in Central Kolkata, Dr. Sarkar said, "It is not the time to summon a few doctors and instigate. Let them question us over our posts. We have the intelligence to answer befittingly. We are clear that we didn't have any malice."

Dr. Goswami said the protests will soar further if their voices are muzzled.

"Our protests can't be muzzled by summoning one or two. If that happens, the protests will further escalate. We will continue protests until justice for Tilottama is delivered," Dr. Goswami said.

Apart from Dr. Sarkar and Dr. Goswami, others in the march were stopped midway. Police escorted the two doctors, who were accompanied by their advocates, to Lal Bazar.

Apart from the two doctors, former Bharatiya Janata Party (BJP) MP Locket Chatterjee was also summoned by the police over social media posts.

One person has been arrested for sharing the picture of the 31-year-old post-graduate medical student who was raped and murdered at Kolkata's RG Kar Medical College and Hospital and for issuing threat to Chief Minister Mamata Banerjee.

More than a week ago, the news of the rape and murder of the junior doctor was reported from RG Kar Hospital bringing the state administration under scanner over the alleged cover-up and fishy investigation by police before the case was handed over to the Central Bureau of Investigation by the Calcutta High Court.

Though the Kolkata Police has arrested one civic volunteer- named Sanjoy Roy- in a quick response to the crime, doctors who are on strike as a protest suspect there were more involved in the incident.

The hospital's initial message to the victim's parents that their daughter committed suicide and the renovation work near the crime scene within hours after CBI's takeover of the case have raised doubts over the state administration's intent.
