An Illinois man has been accused of threatening the prosecutors who won the conviction of R. Kelly on sex-trafficking charges, and was arrested days before the R&B singer's sentencing.

Christopher Gunn, 39, allegedly live-streamed a video on YouTube last October in which he showed a picture of the US Attorney's office in Brooklyn, New York, and named the three female prosecutors who led the Kelly trial.

"We're going to storm they (sic) office," Gunn said in the video, according to a court filing from a Department of Homeland Security agent.

The video showed a shooting scene from the movie Boyz N The Hood.

Citing payment app records, the agent, Ryan Chabot, also said Gunn sold 30 rounds of ammunition related to the matter about June 1.

Chabot said another Cash App user paid Gunn for "30 rounds.. Free R kelly" last August.

"#TheEnterprise I have a spot for us allllll (sic) to link during the trial," Chabot quoted Gunn as posting on June 24, saying the message suggested Gunn had found a place for R. Kelly supporters to gather during the sentencing.

Gunn was arrested on Saturday and is being held without bond. He faces extradition to Brooklyn.

Kelly, 55, was convicted last September for luring women and underage girls for sex.

The trial amplified accusations that had dogged the I Believe I Can Fly singer since the early 2000s.

Prosecutors want US District Judge Ann Donnelly to sentence Kelly to more than 25 years in prison.

Kelly, whose real name is Robert Sylvester Kelly, will be sentenced on Wednesday.
