(Portland, OR) -- A Canadian man has been sentenced to federal prison in the U.S. for running dozens of illegal Asian brothels in three countries, including several in Portland, Tigard and Beaverton. Zongtao Chen recruited women, primarily from China, to travel to the U.S. and work as prostitutes. So-called dispatchers would take requests for "dates" from potential customers and schedule the women who were working in brothels. Chen was arrested in Canada. He pleaded guilty and was sentenced to two years in federal prison.
