All those behind the December 16 gang rape should be hanged, said the father of the 23-year-old victim stressing that he would pursue the case till the end.

As the case against the five accused in the gang-rape of the young woman, who succumbed to her grievous injuries on December 29, began in a Delhi court, her father addressed a press conference on Tuesday to assert that he would approach the courts to ensure justice was done.
