Police said Thursday they detained two Chinese people for arranging prostitutes to sell sex to Chinese tourists here.

The duo, including a 33-year-old Chinese woman, allegedly made 300 million won ($275,000) trafficking sex to an unknown number of tourists since July last year, a spokesman for the Yangcheon Police Station in southwestern Seoul said.

They attracted customers through a Chinese chatting app and took 250,000 won per session.

The prostitutes they recruited turned out to be Chinese, though they had advertised sex with South Korean women.

Interested men were taken to hotels around Seoul and allowed to pick a prostitute they liked among several.

Three prostitutes and a male tourist have been booked without physical detention, authorities said.

Police said they will widen the investigation, adding tour guides as well as the hotels involved may have been part of the crime ring. (Yonhap)
