(Rubicon) A Rubicon man was among 20 people arrested over a three-day period during a prostitution investigation in Oshkosh. That number includes six women and one man from Milwaukee for prostitution and 13 male ‘johns’ for solicitation of sex. In addition to the Rubicon man, the others arrested for solicitation were from Oshkosh, Appleton, Milwaukee, Larsen, Eldorado, Bear Creek, Neenah and Kaukauna along with a San Bruno, California man. Police say some of the men had illegal drugs on them, and one was suspected of illegally possessing a gun as a convicted felon. Officials say one of the female prostitutes had an electronic weapon — and one had a three-month-old child with her, and the baby is now staying with a relative. Two of the suspects went to jail and the remainder had referral arrests made on them to the Winnebago County DA’s Office.
