NEW DELHI (AP) — A Swiss woman who was touring by bicycle with her husband through the central Indian state of Madhya Pradesh was gang-raped by a group of eight men, police said Saturday.

Thirteen men were detained and questioned in connection with the attack, which occurred Friday night as the couple camped out in a forest 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), Gurjar said.

The woman was in a hospital Saturday in the nearby city of Gwalior. She and her husband were fine physically, Gurjar said.

Police detained 13 men and questioned them in connection with the attack, he 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.

India has seen outrage and widespread protests against rape and attacks on women since December’s fatal gang-rape of a young woman in 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.
