The FBI's four-day sweep, searching for pimps and women or girls forced into prostitution, recovered 10 victims 100 suspects.
From July 25-28, the FBI and local law enforcement went undercover and canvassed areas where prostitution occurs. At least 10 of the women approached, admitted they were forced into sex trafficking, some since they were juveniles, and had originally come from Milwaukee.
The victims have now been linked to services, including counseling and housing.
Officers also arrested 100 people thought to have helped coordinate the illegal activities in Wisconsin. Nearly 300 law enforcement agencies here partnered with the FBI.
Milwaukee was among the U.S. cities which topped the list, in terms of juvenile victims rescued. Other cities included San Francisco (12), Detroit (10) and Denver (9).
The four-day sweep was called, Operation Cross County VII. It seeks to rapidly investigate cases in which children are being victimized.
Organizers say the victims were not always found, in their hometowns.
