Police have arrested a third suspect in the gang-rape of two women, including an Israeli tourist, near a Unesco World Heritage Site in southern India.

The women and three male tourists were stargazing near Sanapur lake in Hampi, Karnataka, when they were attacked by three men on Thursday night.

The Israeli and the owner of the homestay she was staying in were assaulted and gang-raped, police said, while the male tourists, including an American, were pushed into the Tungabhadra canal nearby. While two of them survived, a 22-year-old tourist from the eastern state of Odisha was found dead.

Two of the suspects were arrested on Saturday while the third person was detained in the neighbouring state of Tamil Nadu on Sunday.

Karnataka minister Shivaraj Tangadagi said police had been instructed to beef up security to prevent such incidents. “Three people were involved in this horrific crime, which should never have happened. Two were arrested yesterday, and the third was caught today,” he told reporters on Sunday.
