Cook County State’s Attorney Kim Foxx announced Friday that the R&B singer R. Kelly, whose full name is Robert Kelly, was indicted on 10 counts of aggravated criminal sexual abuse — a class two felony — involving four alleged victims.

The indictment accuses Kelly of sexual acts with three children older than 13 but younger than 17. There is no age range listed for one of the alleged victims. The charges say Kelly used force or the threat of force.

His attorney described his client as an innocent man, saying Foxx succumbed to public pressure.

“I think all the women are lying,” attorney Steve Greenberg said. “Mr. Kelly is strong, he’s got a lot of support and he’s going to be vindicated on all these charges — one by one if it has to be.”

Kelly turned himself in Friday night, just hours after Chicago police issued a warrant for his arrest. He arrived in a large, black van wearing a hoodie under an electric blue puffer jacket. As he walked trough a crowd of reporters he was asked questions like “What do you have to say to the fans?” and “What do you have to say to the black women of Chicago?”

Kelly did not respond. Once he entered the building, he was handcuffed and led away by police. His arraignment is set for March 8.
