ST. LOUIS – A man was robbed Monday evening after a sexual encounter with an unknown woman.

According to police, the robbery occurred around 6 p.m. in the 1500 block of Lafayette in the city’s Peabody-Darbust-Webbe neighborhood.

The 59-year-old man told officers he met a woman he did not know and agreed to a sexual encounter with her in his car at a parking lot.
