Serious injuries to her body and brain
The 23-year-old physiotherapy student suffered severe injuries when she was gang raped by six men after she and a male friend boarded a private bus to go home on Dec 16.
She was reportedly beaten and sexually assaulted with a rusting metal bar, which left her with a badly damaged intestine, parts of which had to be removed surgically later. After the assault, she and her companion, who was also beaten up, were stripped and hurled out of the moving bus.
Both were admitted to Delhi's Safdarjung Hospital, where the woman underwent three abdominal operations and suffered a cardiac arrest. Her condition stabilised after a few days but remained critical, Indian media reports said.
Three days after the attack, doctors said the woman could communicate through writing. She was later able to give statements to the local magistrate.
Last Thursday, she was transferred to Singapore's Mount Elizabeth Hospital, where she was found to have an infection of the lungs and abdomen and significant brain injury.
Late last Friday night, Mount Elizabeth Hospital's chief executive Kelvin Loh said doctors were fighting to save her life, including "putting her on maximum artificial ventilation support, optimal antibiotic doses as well as stimulants which maximise her body's capability to fight infections".
The woman died "peacefully" yesterday morning, 13 days after her ordeal.
Dr Loh said she had suffered from severe organ failure following serious injuries to her body and brain.
