The trial of five men charged with gang-raping and murdering a young woman on a bus in New Delhi opened on Tuesday with closed-door testimony from her friend who appeared at court in a wheelchair, still bearing the scars of injuries from the attack.
The 28-year-old software engineer, who may not be identified, is the prosecution's star witness in a case that has triggered nationwide protests, an intense debate about rampant crime against women in India and tougher anti-rape laws.
The five accused are Vinay Sharma, a gym assistant, Ram Singh, the bus driver, his brother Mukesh Singh, bus cleaner Akshay Kumar Singh and fruit vendor Pawan Kumar. They have pleaded not guilty to charges of rape and murder. A sixth accused is being tried separately as a juvenile.
Police allege the six attacked the 23-year-old trainee physiotherapist and her friend on the bus as the couple returned home from watching a movie on Dec. 16. The woman was repeatedly raped and tortured with a metal bar. The couple were also severely beaten before being thrown onto a road.
The woman died of internal injuries in a Singapore hospital two weeks later.
As the trial got under way, the victim's father made a surprise appearance at a news conference organised by the main opposition Bharatiya Janata Party (BJP) to call for his daughter's attackers to be hanged.
At one stage, the friend, defence lawyers and some policemen moved from the courtroom to a courtyard where the bus on which police say the attack took place was parked.
Journalists saw some of them board the vehicle, which was white with tinted windows and orange curtains. Above the windshield was painted "Praise the Goddess" in Hindi.
The victim's friend was not seen boarding the bus. The friend's father said later it was the second time his son had seen the bus since the attack.
In his statement to police after the assault, the friend said their attackers had asked "where are you going with a girl so late at night?" before launching a furious assault in which he was beaten with a metal rod and his clothes ripped off. While he was being beaten, the woman was repeatedly raped, he said, according to a police charge sheet seen by Reuters.
The prosecution says articles stolen from the couple, including their cellphones, rings and debit cards were found in raids conducted on the homes of the accused. DNA evidence and bloodstained clothes also form part of their case.
Defence lawyers say they will highlight what they say are discrepancies in the account given by the victim's friend.
The five men are being tried in a special fast-track court opposite the shopping mall where the victim and her friend went to watch the film "Life of Pi" before boarding the bus.
About 30 policemen were deployed outside the courtroom on Tuesday as the five accused arrived wearing scarves or handkerchiefs to mask their faces.
