A woman from Aberdeen is charged after police in Sioux Falls say she was arrested for prostitution.

Information Officer Sam Clemens says detectives who had been tipped off by an on-line ad contacted the woman.

He says she agreed to a meeting at a hotel in the northwest part of the city, where she was arrested on a prostitution charge.

Clemens identified the woman as Christian Marie Johnson-Berndt, 22, of Aberdeen.

He would not identify the web site where the Street Crimes Unit saw the ad, since police make :"quite a few" arrests from the site.
