An R Kelly fan and YouTuber was arrested in Chicago this weekend over threats he made in a video to “storm” the US attorney’s office in New York following last year’s court hearing in which the musician was found guilty of running a criminal enterprise in order to abuse young people.Christopher Gunn posts content to YouTube under the name DeBoSki, with the strapline “fighting for the due process rights of all people”. He has published countless videos about the prosecution of Kelly, often talking about and criticising witnesses and lawyers involved in the criminal cases against the musician, as well as the judge who oversaw last year’s trial in New York.Gunn’s own arrest relates to a video he made about a week after the guilty verdict was reached in that trial.
