The interior minister said he was also working with security officials to strengthen laws regarding rape and assault.

The brother of the woman killed in the attack said Sunday that their family would like to see a new hospital named after her to keep her memory alive.

He told CNN by phone from eastern India that the family's home village, located in a underdeveloped region, still doesn't have a well-equipped health care center.

"It will be really good if our village gets a hospital in her name. That will keep her memory alive and serve a cause," said the 20-year-old, who asked not to be named.

The rape victim was the eldest of three siblings, with two younger brothers. A physiotherapy student, she was expecting an internship at a hospital in the Indian capital in January.

"After her internship, she would have got a job. And that would have been a great help to our family," said the brother, himself a student.

The family is still struggling with the traumatic loss, he said, and feels that recent protests in several Indian cities in response to the attack are justified.

"You need these protests to bring about a change in laws. And laws should be made so tough that nobody should even think of committing such crimes. Rapists deserve death sentence," he said.
