Another shocking claim against R. Kelly has been made. Last week, a woman told Chicago police that she was sexually assaulted at what she believes was R. Kelly’s former studio.

The unidentified woman says she was picked up in the middle of the night Thursday morning and rushed to the hospital, where she was treated for sexual assault, reports the Chicago Sun-Times.

Police confirmed they had received a report that a woman was raped by three men at a building she later identified as the R&B singer’s music studio — though they’ve been unable to determine the precise location of the assault.

According to reports, the woman told police she was approached by three men in a vehicle while she was at a bar. She then proceeded into the car and was brought to the building, where two of the men sexually assaulted her.

It has yet to be determined whether these men are linked to the disgraced R&B singer, or if R. Kelly even knew about the assault. However, new developments are expected be released this weekend.
