The rapper Nelly will not face rape charges from an October tour bus incident because his accuser is no longer cooperating with prosecutors in Washington state.
The woman had accused Nelly, 43, of raping her on his tour bus in October in a Seattle suburb.
Auburn, Wash., police arrested Nelly, whose real name is Cornell Iral Haynes Jr., on his bus at a Walmart parking lot in the early morning.
He was booked into jail on suspicion of second-degree rape. Shortly afterward, the woman said she wanted to stop the investigation.
King County prosecutors said in a statement Thursday to the Associated Press that they had reviewed the investigation. But, without the woman's help, they could not "proceed or fully assess the merits of the case."
Nelly's attorney, Scott Rosenblum, said in a statement obtained by USA TODAY that the performer had been the victim of a "deceitful allegation devoid of credibility" and would pursue legal action.
"We were confident, that what our investigation revealed from the outset of this allegation would ultimately be clear and Nelly would be vindicated. A thorough investigation did show Nelly was a victim of deceitful allegation devoid of credibility. Credible evidence did show this accuser to be deceptive. We have been in constant communication with the King County authorities and welcomed and appreciated the diligence in which the authorities proceeded. Leaving no stone unturned."
Nelly is a three-time Grammy winner, including for the song Hot in Herre, which won the best male rap solo performance award in 2002.
The following year, he shared a Grammy for the song Shake Ya Tailfeather with Murphy Lee and Sean Combs.
He is also known for the hits My Place and Over and Over. Nelly appeared in the 2005 film The Longest Yard starring Adam Sandler and is the minority owner of the Charlotte Hornets.
