STILLWATER, Minn. (AP) -

A Wisconsin veterinarian is charged with sex trafficking in Minnesota.

Prosecutors in Washington County say Brian Lee Kersten brought young women from China to the U.S. for prostitution. A criminal complaint alleges the 60-year-old Baldwin, Wisconsin veterinarian picked up the women at the airport and drove them to area motels for prostitution.

Authorities say an undercover sting was set up at the Extended Stay Hotel in Woodbury in July after an employee notified police of suspicious activity.

The complaint says officers questioned one woman with the assistance of an interpreter and she told them she had been promised work in a massage parlor after arriving in Minnesota, but instead was taken to the Woodbury hotel.

Kersten posted bail Monday. He did not immediately return a call for comment at his office.
