CHICAGO (AP) — R&B star R. Kelly’s attorney entered not guilty pleas on the singer’s behalf Monday after Kelly was charged with sexually abusing four victims dating back to 1998, including three underage teenagers.

Kelly, one of the best-selling music artists of all time, walked into a Chicago courtroom wearing an orange jail jumpsuit after spending the weekend in the city’s 7,000-inmate jail. Kelly said little during the brief arraignment hearing, telling the judge only that his name was Robert Kelly.

Kelly was arrested Friday on 10 counts of aggravated sexual abuse involving four females, three of whom were minors. He remains jailed after a judge on Saturday set bond at $1 million.

The Grammy Award-winning singer is required to pay 10 percent of the bond, and his attorney said Kelly’s confidants are trying to pay the $100,000 to get him released as he awaits trial.

Among the conditions of release is that Kelly have no contact with females younger than 18.

Jail spokeswoman Sophia Ansaria said Kelly had not posted bail as of late Monday morning. The case was assigned to Cook County Associate Judge Lawrence Flood. Kelly’s next court date is March 22.

Kelly’s attorney, Steve Greenberg, told The Associated Press on Sunday that coordination of the bail payment is complicated. But he said Kelly could be released as early as Monday or Tuesday.

“He has to rely on others acting on his behalf,” Greenberg said. “And it’s just not that easy — because Kelly’s in jail.”

Attorney Michael Avenatti, who said he represents two Kelly victims, said his legal team will give prosecutors a second video on Monday that he alleges shows Kelly sexually assaulting a minor. Avenatti has said he recently gave prosecutors video evidence of the singer having sex with an underage girl.

In arguing for bail within the singer’s ability to pay, Greenberg told a judge over the weekend that Kelly wasn’t wealthy despite decades of success creating hit songs. The lawyer blamed mismanagement, bad contracts and other issues for his client’s financial woes.

There are multiple logistical issues that could have thwarted Kelly’s efforts to pay over the weekend, said Joseph Lopez, a criminal defense attorney in Chicago not connected to the Kelly case. He said court officials must be able to talk to bank officials directly to confirm that an amount written on a check is covered, and that’s not possible when banks are closed.

Records on the Cook County sheriff’s website show Kelly is in Division 8 of the county jail, where the medical unit is located but also where inmates considered at risk from the general inmate population are held, Lopez said.

Disturbing details of the allegations against Kelly emerged Saturday when the prosecution released four detailed documents — one for each accuser — outlining the basis for the charges. The allegations date back as far as 1998 and span more than a decade.
