"I am disgusted, it's a shame," Indian dancer, Uma Sharma, told journalists.

"In a prestigious festival like this, extra precautions should be taken. I don't understand why they start taking care after the incident has happened."

Margaret Skiva, a Polish filmmaker based in Delhi for the past few years, said the city was unsafe for women.

"I am fortunate that I can move around with my husband, otherwise I wouldn't stay here," she told the Indian Express newspaper.

The newspaper said that the attack, coming soon after the alleged rape by members of the presidential bodyguards, has cast its shadow on the entire administration.

"The police, for their part, didn't know where to hide. The scene of the crime is a two-minute drive from the office of the deputy commissioner of police, south district," it said.

Bodyguards

Police have announced a 50,000 rupees ($1,100) reward for any information leading to the arrests of the two men alleged to have attacked the victim.

Lorenzo Amberg, the deputy head of the Swiss Embassy in Delhi, said: "We are hopeful that the culprits will be brought to justice very quickly."

The attacks come just days after a university student was allegedly raped by bodyguards of the Indian president.

Four soldiers have been arrested in connection with that attack.

Last month, a nurse working in a Delhi hospital, was raped, beaten and her eyes gouged out in a ward.
