A Danish woman has alleged that she was gang-raped in the Indian capital of New Delhi - the latest high-profile case of sexual assault against women in the country.

Reports say the 51-year-old woman was in New Delhi for a week and had been visiting touristy sites in Agra and later the National Museum in the capital.

She had lost her way on Tuesday evening on the way to her hotel in Paharganj, a crowded locality in New Delhi where many foreigners stay in affordable lodgings. She was later accosted by a group of men who then assaulted her.

Police said the rapists were "vagabonds" and the tourist was assaulted and robbed of cash and valuables on her person. Her iPad, Euros were taken and she was also beaten. The police have registered a case of rape and robbery.

She had been taken to the Danish embassy in Delhi and she had expressed her wish to return home after a medical examination.

The Delhi police, according to news reports, have detained six suspects based on the complaint made by the woman.

The Danish woman left India on Wednesday morning, according to Delhi police.

Alarming assaults

Frequent news reports of rapes have given cause for alarm at the rate of violence against women in Indian metros.

In December 2012, the brutal gang-rape of a 23-year-old medical student in Delhi had angry citizens protesting across the streets for stringent rape laws and fast track courts to punish the perpetrators.

Political parties such as the Aam Aadmi Party have assured on public platforms to make safety for women a priority.
