During Tuesday's Sioux Falls Police briefing Information Officer Sam Clemens says officers from the department's Street Crimes Unit arrested and charged  20-year-old Johannu Richardson of Phoenix, Arizona with prostitution.

"They were able to find an ad on a website that matched information from the Sioux Falls hotel.   Officers got hold of the woman and eventually she was arrested for prostitution, possession of marijuana and paraphernalia."

Clemens says street crimes officers handle all the prostitution calls in Sioux Falls..

"They've had the training on human trafficking---so that's one of the things they look for when they're dealing with prostitution---if somebody's willing or if somebody else is forcing them in trafficking."

Clemens says Richardson was reportedly working on her own.
