The Nicollet County Sheriff’s office says six have been arrested in a prostitution sting.

Authorities say law enforcement posed as prostitutes online and responded to ads offering sex.

The suspects’ names will be released pending formal charges.

The New Ulm Police Department, Mankato Department of Public Safety, and the Minnesota Drug Task Force are all involved in the case.

Authorities say there have been 116 prostitution-related arrests in Nicollet, Brown, and Blue Earth Counties since November 2014.
