Washington state prosecutors have determined they cannot proceed with criminal charges against rapper Nelly for allegedly raping a woman while on tour with Florida Georgia Line. On Wednesday, the King County Prosecuting Attorney’s Office reportedly told TMZ that it’s impossible to move forward with criminal charges against Nelly, whose real name is Cornell Haynes, Jr., for any crimes due to the alleged victim’s refusal to cooperate with authorities. The woman, who claimed he raped her on his tour bus, told police she didn’t want to press charges after coming forward with her story. >> Read more trending news “Police responded to and investigated a sexual assault allegation involving Mr. Haynes,' a statement from the King County Prosecuting Attorney’s Office, obtained by E!

Not because she did not want the police to charge the celebrity with alleged rape. She wishes she had not called 911 because she believes the system is going to fail her.” Related: Rapper Nelly denies rape allegation, says he is ‘completely innocent’ In October, the rapper was arrested for allegedly raping the woman in his tour bus in an Auburn, Washington, Walmart parking lot while he was touring with the country band Florida Georgia Line.

I am confident that once the facts are looked at, it will be very clear that I am the victim of a false allegation.” “I also want to thank my fans for their unwavering support,” he said in another tweet. “They know me. I assure you I will be vindicated. And I assure you, I will pursue every legal option to address this defaming claim.” Nelly soon responded to the allegations through his attorney, Scott Rosenblum, who said, “Nelly is the victim of a completely fabricated allegation. Our initial investigation, clearly establishes the allegation is devoid of credibility and is motivated by greed and vindictiveness. I am confident, once the scurrilous accusation is thoroughly investigated, there will be no charges. Nelly is prepared to pursue all all legal avenues to redress any damage caused by this clearly false allegation.” Related: Woman who accused rapper Nelly of rape asks police to stop investigation “Her reckless accusation, once investigated thoroughly, was exposed for what it was – a fabrication,” Rosenblum said. “A fabrication that has caused Nelly and his family to suffer emotionally and financially.” Rosenblum indicated that he would like a public apology from he accuser while stating that he would recommend Nelly take legal action against her.
