Police on the Indonesian resort island of Bali have named the captain of a dive boat as a suspect in a fatal scuba diving accident that left at least one Japanese woman dead.

Handoyo Supeno, law enforcement chief at the Bali Police Headquarters, said Thursday the police were also questioning Saori Furukawa, one of the two locally based Japanese dive instructors who were leading five Japanese women on a dive last Friday off the neighboring island of Nusa Lembongan when all seven went missing. He refused to say whether the 37-year-old woman would be declared a suspect.

Furukawa was rescued Monday along with four of her clients, some 75 hours after their group disappeared. The body of the fifth client was found Tuesday, while the other instructor remains missing.
