A woman who went to visit her brother at a hospital in eastern India was allegedly gang-raped by six men Sunday night, police said.

If medical records bear out the woman's account, it will be the latest in a string of such brutal attacks in the country.

On her way home from the hospital, the 25-year-old woman was taken by two hospital custodians to a river bank where she was sexually assaulted by the pair and four other friends, said B.K. Aich, a police superintendent in Mayurbhanj District in Odisha state.

All six were arrested.
