He said he has turned over the video to Chicago prosecutors.
The Cook County State's Attorney's Office tells Yahoo, "We can not confirm nor deny an investigation". "He worked for and had known R. Kelly for decades, and he met the girl on a number of occasions", Avenatti told CNN before releasing a full statement on Twitter regarding his current investigation into the singer.
CNN reports that the tape provided to prosecutors by Avenatti lasts almost 43 minutes and shows a naked man who appears to be R. Kelly performing multiple sexual acts with a girl.
Following the January airing of the "Surviving R. Kelly" docu-series, in which several women accused the singer of sexual abuse and domestic violence, the "Ignition" singer has been faced with mounting sexual misconduct allegations. Avenatti further claimed the video isn't the same evidence used in Kelly's 2008 trial when he was acquitted on child pornography charges.
"My client knows the identity of the girl and R. Kelly". He also claims that "the time frames of the sexual assaults depicted in the video is within in the IL statues of limitations".
Steve Greenberg, Kelly's attorney, was unaware of the newly-surfaced footage.
His alleged behavior came to the media forefront again in July 2017, when BuzzFeed published a bombshell report accusing the star of running a "sex cult" out of his Chicago and Atlanta-area homes.
He added: "Included in the evidence we recently uncovered and recovered is a VHS videotape of Mr. Kelly engaging in multiple sexual assaults of a girl underage".
On Thursday, Avenatti tweeted out a statement describing the tape. "The time has come for him to finally be held accountable for his actions". "We have not been informed about any new information by anyone and we have not been contacted by law enforcement".
According to CNN, the tape's contents are very similar in nature to the videotaped sexual assault on a 13-year-old teen back in February of 2002, although this is a totally different tape and victim. TheGrio has reached out to the Cook County State's Attorney Office for comment and to confirm receipt of the video. DeRogatis, who has reported on Kelly's alleged sexual abuse since 2000, writes that the singer may soon be arrested, according to a senior law enforcement official who has seen the video footage. Six times the girl refers to her genitalia as 14 years old.
