The woman, who flew out of the country this morning, has told the police in a statement that she had sought directions from a group of men to her hotel in nearby Paharganj, when they attacked her at about 4.30 or 5 last evening.
She alleged that they took her to an isolated area, where eight men raped her and robbed her of her iPad mini and all the money, in Euros, that she was carrying.
The Paharganj police said the woman had refused a medical examination. They have registered a case and have rounded up 15 people from the area for questioning.
The police said they were informed by the manager of the woman’s hotel at about 8.30 last night that a guest had allegedly been raped. Paharganj houses many small hotels popular with foreign tourists and students.
In December 2012, the brutal gang-rape of a 23-year-old medical student on a moving bus brought angry citizens out on the roads demanding better safety for women in the capital and more stringent rape laws.
The Centre moved fast to introduce stronger laws, but attacks on women have continued with alarming regularity underscoring how unsafe Delhi still is.
The Aam Aadmi Party, which has formed government in Delhi this month, has listed ensuring safety for women in the capital as a priority.
