JAKARTA (Kyodo) Indonesian police confirmed Monday that a 33-year-old Japanese tourist who was found dead last week on Bali had been raped by her attacker while she lay dying.

I Gede Alit Widana, chief of the Denpasar Police Headquarters in the Bali provincial capital, made the announcement after receiving the autopsy results from the Sanglah General Hospital.

Rika Sano was found dead Sept. 28 in the Kuta resort area after having been reported missing from her hotel three days earlier.

Her suspected killer, David Goltar Wicaksono, 26, was arrested Friday in Malang, East Java Province. "When she was fighting him, the suspect took a log and struck her. When she was dying, the suspect raped her," Widana said. "The suspect possibly suffers from sexual deviation, so we will send him to a psychiatrist."

Widana said Wicaksono is suspected of robbing six women in Kuta in the past six months.

"The suspect was charged with two articles of the Criminal Code, on kidnapping and on murder. He faces five years in jail for each charge," Widana said.

Wicaksono, who has no prior arrests, is still in police custody and being questioned further.

The police earlier said Sano checked into the Prani Hotel in Kuta with her friend, Mayumi Someya, 30, on the night of Sept. 24. At around 2:30 a.m. the following morning, Wicaksono, claiming to be a police officer, led her away from the hotel.

The suspect showed police identification and a badge to the hotel's security officer and claimed Sano was a drug trafficker.

Earlier, he had led Someya away from the hotel and robbed her, but she managed to escape an attempted rape. But when Someya returned to the hotel, she was unable to find Sano.
