An anonymous letter from a St. Charles resident who said he was offered a little something extra after a massage sparked an undercover operation at a Prairie Street business that landed a Chicago woman in police custody on prostituion charges.

Jing Zhang, 50, 227 W. 23rd St., Chicago, was charged March 7 with keeping a place of prostitution, and prostitution. Both are Class A misdemeanors. She was released on her own recognizance pending an appearance at 9 a.m. March 28 in Kane County Branch Court.

According to St. Charles police spokesman Paul McCurtain, the department received the anomymous letter from a resident who went to Marigold Massage, 2075 Prairie St., for a massage. But after the massage, the employee offered additional services for extra money, and the letter writer declined, got dressed, and left. In his letter, he asked police to investigate the incident.

On March 7, 2013, the St. Charles Police Department sent an undercover officer and a surveillance team went to Marigold Massage, police said. An undercover officer went into the business, where he received a massage from the female employee, later identified as Zhang. According to police, after the massage, Zhang offered additional sexual services for an extra fee.

Police arrested Zhang about 3:18 p.m., and transported her to the St. Charles Police Department.

According to police, Marigold Massage remains open. But if there are additional problems in the future at the business, it could be subject to the city’s nuisance abatement ordinance.
