R Kelly Turns Himself In To Police For Sexual Assault Charges

Prosecutors in Chicago charged Kelly with 10 counts of aggravated criminal sexual abuse Friday morning, and 9 of the 10 counts involve alleged victims ranging in age from 13 to 16 years old. There are 4 alleged victims in total, and one of them is the subject of 4 different counts. 

According to the criminal complaint, the allegations include oral and vaginal sex with a girl between the ages of 13 and 17.

Michael Avenatti says the new sex tape he turned over to prosecutors shows R. Kelly engaging in sex acts with a 14-year-old girl -- vaginal sex, oral sex, anal sex and urination.

Avenatti says he's planning to go after R. Kelly's enablers -- lawyers, managers, agents and others whom he says stood idly by and protected the singer as he sexually abused young girls. Avenatti's mission ... bringing them to justice.  

Avenatti also claims Kelly's 2008 trial in which he was found not guilty, was rigged by threats and payoffs. 

R. Kelly is facing a possible 14 years in prison.
