An undercover human trafficking investigation in Oshkosh earlier this week led to nine arrests, including one man from Sturgeon Bay.

The Oshkosh Police Department released details of the investigation Thursday. The investigation was conducted with assistance from the department’s Vice and Narcotics Unit, detectives and patrol officers.

According to the release, the arrests were made Wednesday. The men, who range in age from 20 to 55, are from Oshkosh, Kimberly, Weyauwega, Sturgeon Bay, Sheboygan, Neenah, Fond du Lac and Texas. They were arrested on charges of pandering, defined as persuading, arranging or facilitating another person to become or remain a prostitute.

Police said the charges may be connected to other crimes, including robbery, theft, assault, drug dealing, drug possession and sexual assault.

“The Oshkosh Police Department remains steadfast in our unwavering commitment to combating human trafficking and related crimes, and we continue to work diligently to investigate crimes of this nature,” the release stated.

No further information was available. The department said it works with local nonprofit agencies to provide support for victims of these crimes.
