ST. PAUL, Minn. - A deputy commissioner for the Minnesota Department of Commerce is no longer in the position following an undercover prostitution sting in St. Paul.

Michael Shane Deal, 46, of Litchfield, was arrested Tuesday afternoon. He served as deputy commissioner of the state commerce department’s financial institutions division. On Wednesday night, Minnesota Commerce Commissioner Mike Rothman said Deal's appointment with the department has ended.

“Shane Deal’s appointment with the Commerce Department has ended, effective immediately," read a statement from Rothman. "I am appointing Sarah Butler as the Department’s Acting Deputy Commissioner for Financial Institutions. She currently serves as the Department’s Chief Examiner for Non-depository Financial Institutions and previously served as Deputy Commissioner with the Kentucky Department of Financial Institutions.”

It is not clear if Deal was fired or if he resigned from his post.

Police say Deal was one of five people arrested, all of whom responded to an ad for sex. The sting was part of St. Paul Police's effort to curb human trafficking in the Twin Cities.

Investigators are still working the case. Charges have not yet been filed.
