NBC4 reported that the 52-year-old R&B singer was taken into custody and is expected to be sent to NY, citing two unnamed law enforcement officials.
The Grammy victor, whose real name is Robert Kelly, pleaded not guilty to 11 new sex assault charges last month.
He had been charged with aggravated sexual abuse involving four victims, including at least three between the ages of 13 and 17 years old.
Kelly could face up to 30 years in prison if convicted on those charges.
Chicago police referred all questions on the matter to the USA attorney's office or NY police, but representatives were not immediately available for comment.
It's understood Kelly's spokesman Darrell Johnson will hold a press conference Friday morning in Atlanta. The singer pled not guilty after a court hearing last month.
Kelly's lawyers have argued that she could only have sued up until 2002.
Kelly has pleaded not guilty in both cases and vigorously denied any wrongdoing. "Y'all trying to kill me!" he said as he pounded his chest.
Kelly arrives at the Daley Center for a hearing in his child support case on March 6.
"Believe me, man! This is not me!"
