The Swiss diplomats have attacked Indian government and demanded justice for the victim and her husband, who are on a three-month vacation to the host country.
Sources at Swiss foreign ministry said it is "profoundly shocked" over the incident and termed it a "tragic incident".
Swiss diplomats in India have "demanded that those responsible be quickly identified and brought before the courts," the ministry said. Does Indian government has an answer?
Meanwhile in a statement issued in New Delhi, Switzerland's Ambassador to India, Dr. Linus von Castelmur, said: "The Embassy confirms that the victims reached New Delhi in the early hours of March 17, 2013. They were provided medical assistance on their arrival and are currently recovering".
However, the name of the victims were not revealed to protect their identity.
Media reports on Monday say that six villagers have confessed to gang-raping the Swiss woman. "We have arrested six accused persons who raped the Swiss woman and recovered her mobile," SM Afzal, IG, Chambal Range, told media persons.
The six are identified as Baba, Bhutha, Rampro, Gaza alias Brajesh, Vishnu Kanjar and Nitin Kanjar.
The Swiss couple was on a cycling trip in the hinterland of Madhya Pradesh, when allegedly a group of eight lathi wielding men attacked them at a forest area in Datia district.
The woman was allegedly gang-raped and her husband was thrashed by the men. The attackers also stole the couple's mobile phone, a laptop computer and 10,000 rupees (CHF175).
The woman is said to be in shock. So, is her husband. The 39-year-old woman underwent treatment at a hospital, before she and her husband left for Delhi.
Meanwhile, Madhya Pradesh Assembly was adjourned for the day on Monday following ruckus by Opposition Congress demanding Home Minister Uma Shankar Gupta's resignation on the issue of gangrape of a Swiss woman.
