SEOUL — The operators of a South Korean web broadcasting service where women, mostly North Korean defectors, perform lewd acts have been indicted for circulating pornography, a local prosecutor said on Monday.

The web broadcasting service operated in cooperation with defection brokers in China to find defector women who would be filmed performing sex acts, the Western Branch of the Daegu District Public Prosecutors’ Office said.

Most of the subjects, who are called BJ (Broadcasting Jockey), were North Korean defectors, the suspects told the prosecution. They were forced to perform sex acts in front of webcams under threat of deportation
