Kolkata/IBNS: The students of Calcutta National Medical College on Tuesday blocked former RG Kar College principal Dr. Sandip Ghosh from entering into the campus protesting against the alleged rape and murder of a woman trainee doctor, media reports said.

The West Bengal government on Monday appointed Dr. Ghosh as the principal of Calcutta National Medical College hours after he resigned from the same post at RG Kar Medical College, where the medical student was raped and murdered at the seminar hall.

The students locked Dr. Ghosh's room, denying him entry into the hospital.

Not just the students blocked Dr. Ghosh, they also shouted "Go Back" slogans at Trinamool Congress MLAs Javed Khan and Swarnakamal Saha.

"How can you guarantee a similar incident like what happened in RG Kar will not take place here? We don't want someone like Dr. Sandip Ghosh as the principal," the protesters told Saha in a clear message.

Dr. Ghosh, who faced the ire for alleged mismanagement and financial irregularities at RG Kar Medical College and Hospital, resigned from his post on Monday.

However, the government posted him to CNMC within hours after he reportedly stepped down. Dr. Ghosh had claimed he resigned "willingly" and "not under pressure".

The body of the 31-year-old post-graduate student had injury marks and was recovered under mysterious conditions.

The victim, who hailed from Sodepur near Kolkata, and was pursuing her post-graduation in Chest Medicine. She was on duty on Thursday night.

The initial autopsy report found her body had several injury marks.

The report states that the victim was bleeding from eyes, mouth and private parts. Injury marks were visible on the face, lips, neck, nails, stomach, right-hand ring finger, left leg and left leg ankle, reported The Telegraph.

One person, a civic volunteer named Sanjoy Roy, has been arrested but students suspect there were more involved in the crime.

Police were led to the arrest of Sanjoy by a bluetooth headset which was lying next to the victim's body.

The same bluetooth headset was seen on Sanjoy's neck while entering the building but was missing when he left.

West Bengal Chief Minister Mamata Banerjee, who is facing heat over the incident and subsequent protests, on Monday gave a 7-day deadline to police to solve the case otherwise she will handover it to the central probe agency CBI.
