Indonesian police said Wednesday they have arrested a man suspected of raping an Australian holidaymaker during a robbery at her family's rented villa on the resort island of Bali.

The Indonesian suspect was detained at his rented room in the Balinese capital Denpasar on Monday, said local police chief Reinhard Habonaran Nainggolan.

The 30-year-old, originally from Lombok island which is next to Bali, attempted to flee but police shot him in the leg and detained him, said Nainggolan.

He is suspected of raping the 28-year-old woman, from Perth in Western Australia, in April after breaking into the villa in the popular tourist area of Kuta where she was staying with her family.

The man is accused of threatening the woman with a knife and demanding she hand over her wallet and open the safe in her room, according to police.

When she opened the safe and there was nothing inside, he raped her, they said.

He is also accused of stealing three iPads, two mobile phones and 1.5 million rupiah ($154) from the house.

The woman needed hospital treatment after the attack but was discharged soon afterwards and returned with her family to Australia.
