The student's father told NDTV that he welcomes the government's decision. "This is honouring our daughter, since this is in her memory," he said, adding that the fund should be used to assist women not just in Delhi but across the country.

Six men have been arrested for the gang-rape and murder. Five of them are being tried at a special fast-track court in Delhi. The sixth, who is 17, is being tried by a juvenile court.
