Noted Indian filmmaker Aparna Sen on Tuesday said she felt ashamed over the rape and murder of a PG trainee doctor in Kolkata's state-run RG Kar Medical College and Hospital.

Participating in a protest rally condemning the rape and murder of the female doctor and expressing solidarity with agitating students, Sen said: "I have come here today as a person who lives in Kolkata. I completely support the demands of the students. As a resident of this city, I feel ashamed today."

She urged the state government to act on a war footing to ensure women could work freely in the state.

She said police should be answerable as to why initially they described the incident as a 'suicide' to the parents of the victim.

"The role of police should also come under the ambit of investigation," she said.

She demanded 'exemplary punishment' for the offender who is behind he rape and murder of the female doctor

The Calcutta High Court on Tuesday ordered a Central Bureau of Investigation (CBI) probe into the rape and murder of the PG trainee doctor in Kolkata's state-run RG Kar Medical College Hospital, an incident which has sparked massive protest across the nation.

The court was hearing a batch of pleas including one by the parents seeking a court-monitored probe into the the alleged rape and murder.

The Calcutta High Court on Tuesday ordered controversial Dr. Sandip Ghosh, who was appointed as the principal of Calcutta National Medical College head within hours of his resignation as the head of RG Kar Medical College, to go on a long leave, coming down heavily on the state government in the trainee doctor's rape and murder case that has sent shockwaves across the country.

"The Principal is the guardian of all doctors working there... if he doesn't show any empathy who will show? He should be at home not working anywhere...," Chief Justice TS Sivagnanam said as quoted by NDTV.

"... this Principal will not function... let him go on long leave. Otherwise we pass an order," the court said.

Meanwhile, the parents of the RG Kar Medical College and Hospital's trainee doctor, who was raped and murdered at the seminar hall, claimed they were told that their daughter died of suicide by the state authorities, media reports said.

Alleging gross insensitivity in dealing with the heinous crime, the parents told the Calcutta High Court on Tuesday as quoted by NDTV, "We were told at 9.30 pm she was unwell... then (told) she committed suicide. The hospital did not allow me to see my daughter."

Students prevent Ghosh from entering Calcutta National Medical College

Meanwhile, 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 the medical student.

The trainee doctor was allegedly raped and murdered at the seminar hall of RG Kar Medical College and Hospital, which is located in North Kolkata's Belgachia area.

One person, a civic volunteer, has been arrested in connection with the case but protesting students suspect more people are involved in the case.

Slamming the state government and administration, the court wondered how Dr. Ghosh stepped down and was "rewarded with another responsibility?"

"...why do you protect (him)? Let him tell the truth... something is missing here," the court thundered as reported by NDTV.

The high court has asked for the case diary by 2 pm and directed the filing of Dr. Ghosh's resignation letter. "We want to see what he has written," said the court.
