SEOUL, Nov. 17 (Yonhap) -- Police said Thursday that they have arrested a broker who allegedly used the Internet to arrange perverted sex and booked 70 others, including distinguished figures like doctors and professors, for being involved in the illegal prostitution ring.

The 41-year-old man, surnamed Park, was arrested on charges of operating several Internet sites that sold the services of women, mostly housewives, to male members from 2008 and until September, officials at Gangnam Police Station in southern Seoul said.

Park collected 68 million won ($60,100) in membership and brokerage fees from men who used his sites, sometimes arranging perverted group sex at motels in suburban areas, officials said.

Seventy others were booked without physical detention on charges of buying or selling sex through the Web sites. Among those booked were professors, doctors and other professionals, as well as several ordinary housewives, they added.

South Korea prohibits prostitution by law.
