More protests outside R. Kelly's Chicago studio

CHICAGO (Fox 32 News) - Dozens of people gathered outside singer R. Kelly's studio in Chicago on Saturday to demand that he be held accountable for alleged sex crimes.

On Friday, Chicago Police came to Trump Tower to investigate reports that Kelly was holding women there against their will. Police said the women claimed they were there voluntarily.

The renewed attention on Kelly's behavior comes after a Lifetime TV documentary in which several women claimed they were kept captive and sexually assaulted.

The studio is located at 219 N. Justine on the city's West Side. The Sun-Times reports that city attorneys believe it is being used illegally, against city zoning designations. The studio is in a manufacturing district and cannot be used as a music studio or residence.

Kelly's attorneys say the claims of abuse are false. Kelly has previously been acquitted of child porn charges in Chicago.
