Delhi rape case: Defendants face first witness evidence
Five men accused of the abduction, rape and murder of a student in the Indian capital, Delhi, have been hearing the first witness evidence in their trial.
The 23-year-old student's male friend, who was also attacked, was the only witness at Tuesday's hearing.
The five accused deny the charges. If convicted, they could face the death penalty. A sixth suspect is to be tried by a juvenile court.
No reporting was allowed of Tuesday's proceedings, which have now ended.
The assault has outraged India and sparked a debate about the treatment of women.
The physiotherapy student's male companion was the first of some 80 witnesses to be produced by the prosecution at Saket District Court, a specially convened fast-track court.
All reporting of proceedings inside the courtroom has been banned and the judge has ordered lawyers not to speak to reporters.
The male companion will be cross-examined by the defence on Wednesday.
He was with the student when she was attacked on a bus and thrown from the vehicle.
She died in a Singapore hospital on 29 December from her internal injuries.
The woman and her 28-year-old companion cannot be named for legal reasons. He arrived at the courthouse in a wheelchair, still unable to walk properly due to injuries suffered in the attack.
His father, who accompanied him into the court complex, told Agence France-Presse news agency: "My son will go to any lengths to ensure that the guilty are punished."
The bus believed to have been used in the attack was driven into the court complex on Tuesday.
The five defendants facing trial in the Saket fast-track court are Ram Singh and his brother Mukesh, Pawan Gupta, Vinay Sharma and Akshay Thakur.
They face 13 charges, including murder, gang-rape, kidnapping and destruction of evidence.
Prosecutors say they have extensive forensic evidence, supported by the suspects' mobile-phone records and the testimony of the dying woman and her companion.
Defence lawyers are expected to argue that the forensic evidence has been fabricated and that the rush to prosecute has led to an unsafe trial.
The sixth suspect, who is 17, will face trial in a juvenile court.
The maximum sentence he would face if convicted would be three years in a reform facility.
The BBC's Sanjoy Majumder in Delhi says the case is being closely followed in India, where it has led to massive protests about the treatment of women and how the police and legal system tackle sex crimes.
On Sunday, Indian President Pranab Mukherjee signed a new anti-rape law which has increased the minimum sentence for those convicted of gang-rape and allows for the death penalty to be used in extreme cases.
But women's groups have come out against the new law, saying that marital rape and sexual assaults by Indian security forces in conflict zones should have been included.
