Phnom Penh - Cambodian police said on Wednesday they had arrested a Canadian man who allegedly sexually abused two young girls in the costal resort town of Sihanoukville.

Police arrested 68-year-old Daniel Lavigne on a tourist bus travelling from Sihanoukville to Phnom Penh on Monday after he allegedly sexually abused two sisters aged 10 and 12.

Regional migration police chief Som Saruen said Lavigne had confessed to "indecent acts" against the children but denied having sexual intercourse with them.

Lavigne told police he was a boyfriend of the girl's mother, who police said was also being investigated.

Som Saruen said Lavigne was scheduled to appear before a court and be formally charged on Thursday. (dpa)
