He said that the family would be content only after all the accused were given capital punishment.
Six persons, including a juvenile, had brutally gangraped and assaulted the 23-year-old paramedic in a moving bus in south Delhi on December 16, last year.
The victim had died in a Singapore hospital on December 29.
While one accused had allegedly committed suicide in Tihar jail, the juvenile was sentenced to three years in reform home, the maximum punishment for under-age criminals for any offence.
After being sentenced to death by a trial court in September, the other four accused Akshay, Vinay, Pawan Gupta and Mukesh are facing trial in Delhi High Court.
