The body of a woman whose gang rape provoked violent protests in India arrived in New Delhi early Sunday.

The 23-year-old unidentified woman died of severe organ failure in a Singapore hospital after suffering internal injuries and brain damage in the attack.

Indian authorities have charged six men with murder. Police say the men could face the death penalty if convicted.

Candlelight vigils have been held in New Delhi and many cities across India. The protesters demanded justice for the victim and safety for women.

New Delhi has been rocked by mass protests since the woman was attacked December 16.

The woman is reported to have been traveling with a male companion on a charter bus in New Delhi when the six men on board beat them both with an iron rod. The woman was raped repeatedly. Reports say the rod was used in the rape. The woman and her friend were then thrown from the moving vehicle.

The male friend survived the attack.
