, the student and her male friend were returning after watching a film in a shopping centre in South Delhi, where they were attacked and dumped by the roadside near the domestic airport after the nearly 40-minute ordeal.
The couple have been admitted to the hospital. The woman has undergone two rounds of surgery since Sunday.
The doctors at Delhi’s Safdarjung Hospital treating the woman said their focus was on providing her the best treatment as her life was at grave risk. She underwent surgery to remove a gangrenous section of intestine, and there was risk of infection. She remained in a critical but stable condition.
Protests have been taking place at India Gate and outside Congress President Sonia Gandhi’s 10 Janpath residence over the devious crime on Sunday night.
Indian police have used tear gas and water cannons to keep back thousands of protesters marching in Delhi over the brutal gang rape.
Six people are arrested in connection to this gangrape.
The government has come under tremendous pressure from opposition MPs, students and women's rights activists, with many accusing the authorities of not doing enough to stop crimes against women.
The government has tried to halt the rising anger over the attack by announcing a series of measures intended to make Delhi safer for women.
They include more police night patrols, checks on bus drivers and their assistants and the banning of buses with tinted windows or curtains.
