PHNOM PENH, August 6, 2008 (AFP) - Cambodia sentenced an American man to more than two years in prison for committing indecent acts against minors, and has arrested a Frenchman accused of abusing boys, officials said Wednesday.

The American, Thomas Wayne Rapanos, was sentenced to two and a half years in prison after being convicted of committing indecent acts against minors, said judge Din Sivuthy.

Rapanos, 55, was arrested in March after police raided a guesthouse and found a 12-year-old Vietnamese girl and a 16-year-old Cambodian girl in his room.

Rapanos held a Bible and cried outside the courtroom before the judge issued the verdict.

'I am 100 percent innocent,' he told reporters as he was led off to prison.

Frenchman Michel Roger Blanchard was arrested Monday for sexually abusing four Cambodian boys aged between eight and 18, said Major General Bit Kimhong, the country's top anti-trafficking official.

Blanchard, 43, was arrested at his rental home in the popular seaside town of Sihanoukville on charges of committing sexual and indecent acts against minors, the official said.

Cambodia has struggled to shed its reputation as a haven for paedophiles, putting dozens of foreigners in jail for child sex crimes or deporting them to face trial in their home countries since 2003.
