Aside from arresting Edward Walker, 46, in Miami-Dade, agents also arrested Richard Walker and Tiphani Pereira for sex trafficking in Broward County.
According to FBI Special Agent Joseph Oliver, an undercover officer responded to an ad on the Mega Personals site.
The officer paid $240 to meet a sex trafficking victim for 30 minutes at the Crossland Economy Studios in Fort Lauderdale, according to the complaint.
Edward Walker, who is not related to the Richard Walker case in Broward County, faces a federal charge of sex trafficking a minor or by force, fraud or coercion.
Records show Richard Walker also faces a charge of false statements to a federal officer charge after denying his involvement despite the evidence.
