BHOPAL, India - Police have arrested six men accused of the gang-rape of a Swiss tourist who was camping with her husband in an Indian forest in the central state of Madhya Pradesh.

All the accused will go before a magistrate on Monday, Dilip Arya, deputy inspector general of police, told Reuters. Police have also recovered the couple's valuables.

The assault on the 39-year-old Swiss woman on Friday night came three months after a 23-year-old physiotherapy student was gang-raped and beaten in a moving bus and thrown bleeding on to the street in a case that sparked outrage in the country. She died later in hospital in Singapore.

 

The latest incident has again turned the spotlight on the security of women in India, the world's largest democracy.

One woman is raped every 20 minutes in India, according to the National Crime Records Bureau. But police estimate only four out of 10 rapes are reported, largely due to victims' fear of being shamed by their families and communities.

The Swiss woman and her husband were touring the state by bicycle and were camping overnight in the forest. Arya told Reuters on Saturday that seven men attacked the couple in their tent and four of them raped the woman.

However, police investigation later found out that only six people were involved in the crime, he said.

Those arrested are identified as Baba, Bhuta, Rampro, Bishnu, Gaja and Nitin. They all aged between 20 and 25 years and belong to a local tribe known as the Kanjar, Arya said. They were also carrying a firearm.

No information was immediately available on the defendants' account of events.

The woman and her husband have left the state and are now at the Swiss embassy in New Delhi.

"A decision regarding the next steps to be made in the interest of the two concerned Swiss citizens will be made with them in due course," a spokesman for the Swiss Ministry for Foreign Affairs said in a statement.

After the physiotherapy student was raped and beaten in Delhi last December, millions of Indians took to the streets demanding the death penalty for her attackers and official action to reduce the number of assaults on women.

Four men and a juvenile are on trial for that attack. A sixth defendant, who police say was the ringleader, was found dead in his cell last Monday.

A Swiss woman who was on a cycling trip in central India with her husband has been gang-raped by eight men, police said Saturday. The attack comes three months after the fatal gang-rape of a woman aboard a New Delhi bus outraged Indians.

Authorities detained and questioned 13 men in connection with the latest attack, which occurred Friday night as the couple camped out in a forest in Madhya Pradesh state after bicycling from the temple town of Orchha, local police officer R.K. Gurjar said.

The men beat the couple and gang-raped the woman, he said. They also stole the couple's mobile phone, a laptop computer and 10,000 rupees ($185).

The woman, 39, was treated at a hospital in the nearby city of Gwalior, Gurjar said.

A photo showed the woman walking while being escorted by police to the hospital. Her face was concealed with a hood, a common practice in India, where law does not allow rape victims to be identified publicly to protect them from the stigma attached to rape in the conservative country.

Police detained 13 men and questioned them, Gurjar said. Six of the men were released after questioning. No other details were immediately available.

Indian television stations showed scores of police searching the forest where the attack occurred.

Swiss Foreign Ministry spokesman Tilman Renz described the case as "deeply disturbing" and said Swiss diplomats were assisting the couple.

The diplomats called on Indian authorities "to do everything to quickly find the perpetrators so that they can be held accountable," Renz said in a statement.

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.

India has seen outrage and widespread protests against attacks on women since December's fatal gang-rape of a young woman on a moving bus in New Delhi, the capital. The crime horrified Indians and set off nationwide protests about India's treatment of women and spurred the government to hurry through a new package of laws to protect them.

One of six suspects in the December attack was found dead in a New Delhi jail this past week. Authorities said he hanged himself, but his family and lawyer insisted foul play was involved. A magistrate is investigating. Four other men and a juvenile remain on trial for the attack.

Swiss voters rejected a proposal to increase employees' annual minimum paid vacation entitlement to six from four weeks on Sunday after firms warned it might hurt competitiveness and threaten jobs.

The initiative was put forward by trade union Travail.Suisse, which argued that four weeks' vacation was insufficient because the pressure of work had increased so much in recent decades, causing rising stress and health problems.

But Swiss television said initial figures showed the proposal had been rejected by a clear 67 percent of voters.

Referendums are central to Switzerland's political system of direct democracy, and have been held on topics ranging from health insurance to smoking bans.

In a separate referendum Sunday, people in Zurich voted for the creation of “sex boxes” -- places where prostitutes can work -- while Geneva residents agreed to restrict street protests, BBC News reported.

The “sex boxes” -- as they have been nicknamed by local people -- are parking spaces with walls between them where sex workers can operate away from suburban areas, according to the BBC.

The Swiss have a reputation in Europe for being efficient and hard-working, a trait that has helped the country attract international companies and do well in competitiveness rankings.

'Fear-mongering campaign'
The Travail.Suisse union said the referendum had taken place at a bad time because of serious economic concerns surrounding the euro zone crisis.

"For many voters, it was understandable that current concerns about their own jobs took precedence over the long-term welfare of people and Swiss business," it said in a statement. "With their fear-mongering campaign, the opponents of the initiative played with the uncertainty of workers."

The main employers' association, which had lobbied hard against the proposal, welcomed the result.

"The 'no' to the holiday [vacation] initiative means above all a 'yes' to the maintenance of the competitiveness of Swiss companies and the securing of jobs," it said in a statement.

"Adoption of the initiative would have pushed up already high labor costs in Switzerland and burdened business with additional costs of six billion Swiss francs ($6.5 billion) a year," the statement added.

Average Swiss vacation entitlement is already around five weeks, as many firms offer more than the statutory minimum. In 2002, Swiss voters rejected a proposal to cut the working week to 36 hours from 42 hours.
