The father of a student who was brutally raped on a New Delhi bus called for her attackers to be hanged as a group of five men were charged in court Thursday in the rape and murder.

The attack on the 23-year-old woman, who died of severe internal injuries over the weekend, has provoked widespread protests across India.

Prosecutor Rajiv Mohan filed a case of rape, tampering with evidence, kidnapping, murder and other charges against the men. The charge sheet was not released and he asked for a closed trial. A hearing was set for Saturday.

The father of the victim, who has not been identified in accordance with Indian law, said he backed calls for the attackers to be executed, according to Reuters.

"The whole country is demanding that these monsters be hanged. I am with them," the father purportedly told reporters in his home village of Mandwara Kalan in Uttar Pradesh state.

The men charged were Ram Singh, the bus driver; his brother Mukesh Singh, who cleans buses for the same company; Pavan Gupta, a fruit vendor; Akshay Singh, a bus washer; and Vinay Sharma, a fitness trainer. They did not appear in court. Authorities have said they would push for the death penalty for the men.

A sixth suspect, listed as a 17-year-old, was expected to be tried in a juvenile court, where the maximum sentence would be three years in a reform facility. Police also detained the owner of the bus on accusations he used false documents to obtain permits to run the private bus service.

The Bar Association said its lawyers would not defend the suspects because of the nature of the crime, but the court was expected to appoint attorneys to defend them.

"Strict, strict, strict punishment should be given to them," said Ashima Sharma, an 18-year-old student attending a protest Thursday. "A very strict punishment ... that all men of India should be aware that they are not going to treat the women like the way they treated her."

The woman was attacked Dec. 16 after boarding the bus with a male companion after watching an evening showing of the movie "Life of Pi" at an upscale mall. The vehicle was a charter bus that illegally picked up the two passengers, authorities said.

The pair were attacked for hours as the bus drove through the city, even passing through police checkpoints during the assault. They were eventually dumped naked on the side of the road. The woman, whose name was not released, was assaulted with an iron bar and suffered severe internal injuries that eventually proved fatal.

The attack caused outrage across India, where women are routinely subject to everything from catcalls to assaults. Many say they fear being outside at night.

Outside the court, about 50 woman lawyers held a protest, demanding wholesale changes in the criminal justice system to ensure justice for women. `'Punish the police, sensitize judiciary, eradicate rape," read one protester's sign.

Indian Chief Justice Altamas Kabir said the accused should be tried swiftly, but cautioned that they needed to be given a fair trial and not be subjected to mob justice.

"Let us not lose sight of the fact that a person is presumed innocent until proven guilty," he told reporters Wednesday, while inaugurating the new fast-track court. "Let us balance things. Let us not get carried away. Provide justice in a fair but swift manner so that faith of people is once again restored that the judiciary is there behind the common man."

Many cases never even get to court because of intense social pressure against families reporting sexual assaults, which are often blamed on the female victims. When women do report rapes, police often refuse to file charges and pressure the victims to reach a compromise with their attackers.

To try to rectify that, Home Minister Sushilkumar Shinde announced a special recruitment drive for women police officers Thursday and ordered every police station in the capital to be staffed by at least nine female officers to make them more attentive to women's needs.

In a sign attitudes might be changing, and that even powerful men are being held accountable, police in the northeastern state of Assam arrested a leader of the ruling Congress party Thursday on accusations he raped a woman in a village in the early hours of the morning.

Footage on Indian television showed the extraordinary scene of local women surrounding the man, ripping off his shirt and repeatedly slapping him across the face.

Police said the man, Bikram Singh Brahma, was visiting the village of Santipur on the Bhutan border when he entered a woman's house and raped her at 2 a.m. Amid the screams, villagers ran to the home and captured the man, said G.P. Singh, a senior police officer in the area.

"We are taking this issue very seriously," Singh said.
