Last month, the Swiss government issued a travel notice for India that included a warning about "increasing numbers of rapes and other sexual offenses" in the South Asian nation, and the latest incident could prompt other countries to issue similar warnings.
On Monday, the Press Trust of India news agency reported that the 39-year-old woman said she will stay in India for now to help the investigation. There was no immediate confirmation and phone calls to the Swiss Embassy went unanswered.
Indian Tourism Minister K. Chiranjeevi met the Swiss ambassador to assure him that the victim would receive justice, a statement from his office said. Chiranjeevi also said the Indian government needs to do more to ensure that tourists inform local police stations before venturing into remote areas.
After last December's bus attack, the government passed a law increasing prison terms for rape from the existing seven to 10 years to a maximum of 20 years. The law provides for the death penalty in cases of rape that result in death or leave the victim in a coma. It has also made voyeurism, stalking, acid attacks and the trafficking of women punishable under criminal law.
