If you place an ad in the escort section of Backpage.com, there's a good chance you might hear from an undercover officer or agent.
Law enforcement around Oklahoma have been using the popular website for a while and have made a lot of arrests.
The latest example happened Thursday night in the area of East 21st and South 129th.
They told the agent Marlon Penn (A.K.A. "Rio") had been pimping them out.
Tulsa police say an undercover agent answered one of the ads and a meet was setup. When the agent arrived at the scene, he ended up meeting three different females who were working as prostitutes.
Additionally, two of the females stated "they were fearful of Rio." Police say their fear of Penn, caused them to continue to work for him as prostitutes.
Penn was arrested and taken to the Tulsa County Jail. He faces a count of human trafficking.
