Police descend on a small village in central India following the brutal gang-rape of a Swiss woman.

The 39-year-old was attacked and robbed not far from here while camping with her husband on Friday.

Now police in the state of Madhya Pradesh say they are close to arresting four people for the crime.

They said a DNA test would be carried out on the attackers, and vowed they would be punished.

The rape comes three months after another brutal assault triggered nationwide protests.

Tens of thousands of Indians took to the streets after a 23-year-old woman was gang-raped on a moving bus.

She later died from her injuries, a victim of what advocates say is an epidemic of sexual assault in the world's second-most populous country.
