Authorities say R&B singer R. Kelly was taken into custody during a hearing in Chicago over unpaid child support.

Kelly left the courtroom with his lawyers on Wednesday through a different door than he had entered. His hands weren’t cuffed.

Cook County Sheriff’s Office spokeswoman Sophia Ansari says Kelly was taken into custody and will be transferred to the county jail. She says she doesn’t know the reason he was taken into custody, including whether it had to do with unpaid child support he owes.

Kelly was charged last month with 10 counts of aggravated sexual abuse pertaining to four women years ago, including three who were underage at the time.

The singer has denied wrongdoing and pleaded not guilty.

On Wednesday morning, an interview he did with Gayle King aired on CBS This Morning.

Kelly was emotional, saying he’s being “assassinated” and he denied sexually abusing women and controlling their lives.

At one point during the interview, Kelly stood up and ranted, saying, “I have been buried alive, but I’m alive.” He said he needs someone to help him “not have a big heart.”

He said all of his accusers are lying.

The R&B singer said he’s done “lots of things wrong” when it comes to women, but he said he’s apologized. He denied doing anything against their will.

The singer believes social media is to blame for creating the allegations against him.
