Los Angeles ­­­­- A Long Beach man was arraigned Monday in federal court for coercing women to engage in prosecution, according to authorities.

Roshaun "Kevin" Nakia Porter, 36, operated a prostitution ring in the Orange County area and meets potential victims by placing ads on Craigslist.com and with Seekingarrangments.com, law enforcement authorities allege.

The women believed they were entering into an monogamous relationship with Porter, say officials. They claimed that Porter maintained a romantic relationship with them and then, forced them into prostitution, according to law enforcement.

During a sting operation, law enforcement officers said they found five women who claimed Porter was forcing them to work as prostitutes.

Porter allegedly threatened to find them and hurt their families if they tried to leave, authorities allege.

A federal grand jury on April 25 indicted Porter with two counts of forced labor and two counts of sex trafficking by force, fraud or coercion.

Law enforcement officials believe Porter may have additional victims. Anyone with information about victims may contact the FBI at 310-477-6565.
