New Delhi - A woman was allegedly raped by three men in a car that was driven through New Delhi before she was thrown out of the vehicle in the city's suburbs, police said Tuesday.

The woman, aged around 35, was abducted by the men from New Delhi's satellite city of Gurgaon on Monday night.

Police said the suspects sexually assaulted her in the car as they drove through parts of the Indian capital and then threw her from the vehicle in Noida, on the outskirts of New Delhi early Tuesday.

Local media reported that the woman was unconscious when she was thrown from the car and the police was informed when a passerby noticed her lying by the side of the road.

"The victim was taken to hospital for treatment and medical examinations. She later accompanied police teams to the places she was abducted from and where the crime took place," Noida police chief Love Kumar said by phone.

"We have launched investigations on the basis of her complaint and are trying to get the CCTV footage from these areas. No arrests have been made yet," he added.

The assault raises fresh questions about the safety and security of women in the Indian capital. Sexual violence has been a focus of public attention in India since the gang-rape and murder of a student in New Delhi in 2012. Despite the enactment of tougher laws, the attacks on women have continued unabated.
