OSAKA -- A 37-year-old Japanese man was arrested Monday on suspicion of paying for sex with a 14-year-old Vietnamese girl in Cambodia, marking the first time a domestic law banning sex with children has been applied to an offense committed abroad, police said.

Takeshi Ozawa, a resident of Kasugai, Aichi Prefecture, has admitted to paying the girl $550 for a week's worth of services and having sex with her from Dec. 30 last year to Jan. 4 at a hotel in Phnom Penh, despite knowing she was a minor, police said.

They said the act was discovered after hotel employees informed local police.
