Twenty-one people have been arrested in a sex trafficking ring with ties to Las Vegas.
Authorities have called it a sophisticated sex trafficking ring that brought hundreds of women from Thailand to America and forced them to work as prostitutes.
Authorities say the members of the ring also laundered millions of dollars in earnings. The indictment was unsealed Thursday and says the sex-trafficking ring started in 2009.
Women were brought from Bangkok, Thailand to several U.S. cities, including Los Angeles, Chicago, Las Vegas, Phoenix, Minneapolis, Washington, Houston, and Dallas. The women were lured with promises of a better life but were forced to work as modern-day sex slaves until they paid back bondage debts.
