Singer R. Kelly was taken into custody Thursday night by the New York Police Department and federal Homeland Security agents on sex trafficking charges.

"R Kelly was arrested in Chicago tonight on charges contained in a 13-count indictment returned today in the Northern District of Illinois," the attorney's office said in a statement following his detainment. "The indictment includes charges of child pornography and obstruction of justice."

CBS News also reports the 52-year-old's residence in Chicago's Trump Towers was raided by federal authorities Friday morning. Kelly was walking his dog at the time of his arrest.

Per the news site, a separate five-count arraignment was also delivered by the Eastern District of New York for accusations of racketeering. The trial for those charges will be held in Brooklyn at another date.

Kelly's legal battles have spanned nearly two decades, with various parties accusing the "I Believe I Can Fly" singer of sexual misconduct and inappropriate relationships with teenage girls. His most recent charges included 11 counts of sexual abuse and aggravated criminal sexual assault in May, which NBC News writes comes with a punishment of between six and 30 years behind bars. Prior to that, Kelly was accused in February of aggravated sexual abuse of four women between 1998 and 2010. He was released on a $1 million bond and ordered to cease communication with any individuals under 18 years of age.

According to a statement from his crisis manager, Kelly vehemently denies any wrongdoing on his part.

"When you’re innocent of charges — and Mr. Kelly has declared his innocence — in America, you know and I know, that you’re innocent until proven guilty," Darrell Johnson said to NBC News Friday. "And he's said many times that he's innocent."
