Anti-human trafficking police in Phnom Penh captured Yem Asisal and her stepfather Nhem Phally in the Cambodian capital on Tuesday in what was their first success in cracking down on organ trafficking, Xinhua reported on Wednesday.
"They face charges of people trafficking for the purpose of organ removal," Keo Thea, chief of the police unit told the Chinese news agency.
The arrest followed complaints filed by five victims who were sent to Thai hospitals with forged documents to have their kidneys removed, the officer said.
A kidney was sold for US$10,000 (325,000 baht) but each victim received only between $3,000 and $5,000, he said.
The two could be jailed for up to 15 years if found guilty.
