Singapore/New Delhi, Dec 28 : The 23-year-old woman who was gang raped on December 16 and admitted to Singapore's Mount Elizabeth Hospital on Thursday morning, remains in an extremely critical condition, say doctors treating her.

The para-medical student was gang-raped and brutally tortured by a group of six people on the night of December 16.

The plane carrying the girl landed at the Changi International Airport at 7.30 a. m. local time, the Indian High Commission in Singapore said.

A statement issued by the Mount Elizabeth Hospital said: "The condition of the patient remains extremely critical. Before she was admitted to our hospital she had undergone three abdominal surgeries and had experienced a cardiac arrest in India. A multi-disciplinary team of doctors is taking care of her and taking all possible steps to stabilise her condition."

The rape victim was shifted to Mount Elizabeth Hospital, which has a state-of-the-art facility for multi-organ transplant, after doctors attending on her decided that she should be taken there for treatment that could last for several weeks.

Dr. B. D. Athani, Medical Superintendent of the Safdarjung Hospital, had said that she was given "the best of the available medical aid" during her 10-day treatment at the hospital.

The young woman has already been operated upon thrice and had her small intestine removed due to extensive injuries following the brutal torture by the five men and a juvenile who raped her in a moving bus.

On Tuesday she gave a statement to a magistrate - for a second time following complaints of alleged police interference the first time it was recorded on December 21.

The Home Ministry also ordered a probe into the circumstances in which the first statement was recorded following a complaint by Delhi Chief Minister Sheila Dikshit. Delhi Police chief Neeraj Kumar denied charges that police had tried to influence the magistrate. (ANI)
