The woman's body is being taken to her village in Uttar Pradesh's Unnao district in an ambulance.
The brother of the Unnao rape victim said his sister will get justice when all the accused go to the place "where she has gone".
"She told me, brother please save me. I am very sad that I could not save her," he told reporters on Saturday.
He said the persons involved in the incident should be either killed in an encounter or hanged.
