BROOKLYN -- US singer R Kelly has been found guilty of exploiting his superstar status to run a scheme to sexually abuse women and children over two decades, BBC reported.

Jurors in Brooklyn federal court deliberated for a little more than a day before voting to convict the 54-year-old Kelly on all nine counts he faced, after a six week trial.

Kelly kept his head down as the verdict was read, with his face shielded by a white mask.

Eleven accusers, nine women and two men, took the stand over the searing trial to describe sexual humiliation and violence at his hands.

After two days of deliberation, the jury found Kelly guilty on all the charges he was facing.

The jury found Kelly, whose full name is Robert Sylvester Kelly, was the ringleader of a violent and coercive scheme that lured women and children for him to sexually abuse.

The singer - most famous for the award-winning song I Believe I Can Fly - was also found to have trafficked women between different US states and produced child pornography.

Deveraux Cannick, a lawyer for Kelly, told reporters that the defense was disappointed. "I'm sure we'll be appealing," he said.

Kelly faces a mandatory minimum of 10 years behind bars, and could face up to life in prison at his May 4, 2022, sentencing.

Along with eight counts of sex trafficking, Kelly was found guilty of racketeering -- a charge normally used against organized crime associations.

During the trial prosecutors detailed how his managers, security guards and other entourage members worked to assist him in his criminal enterprise.

One woman who testified that Kelly imprisoned, drugged and raped her said in a written statement after the verdict that she had "been hiding" from Kelly due to threats made against her since she went public with her accusations.

"I'm ready to start living my life free from fear and to start the healing process," added the woman, identified in court as Sonja.

Another woman who testified in court, Lizette Martinez, said she was "relieved" by the verdict.

"I'm so proud of the women who were able to speak their truths," she added.

Legal documents have revealed the mental torment that Kelly subjected his victims to. They were not allowed to eat or use the bathroom without his permission, he controlled what clothes they wore and made them call him "Daddy".

Gloria Allred, a lawyer who represented several victims, told reporters: "I've been practicing law for 47 years. During this time, I've pursued many sexual predators who have committed crimes against women and children.

"Of all the predators that I have pursued, Mr Kelly is the worst."

At a news conference outside the court on Monday, prosecutor Jacquelyn Kasulis said that the jury had sent a message to other powerful men like Kelly.

"No matter how long it takes, the long arm of the law will catch up with you," said Ms Kasulis.

The verdict comes 13 years after Kelly was acquitted of child pornography charges after a trial in the state of Illinois.

Many of the allegations heard in the trial were first laid out in the 2019 documentary Surviving R Kelly.

Victims were sometimes selected from his concert audiences, or were enticed to join him after being offered help with their fledgling music careers after chance encounters with the singer.

But after joining his entourage, they found that they were subjected to strict rules and aggressively punished if they violated what his team had dubbed "Rob's rules". -- Agencies
