Cristiano Ronaldo's reputation has been tainted by a former teacher accusing him of raping her a decade ago.
He did not face criminal charges over the incident in the US — but The Sun can reveal his DNA was matched to evidence in the case.
Among 100 pages of emails between police and prosecutors on the criminal case, which has since been dropped, Vegas detective Jeffrey Guyer wrote: “DNA is back and is a match.”
And Ronaldo told his lawyers Ms Mayorga said “no” and “stop”, leaked emails claim.
Now Ms Mayorga, 34, is pursuing a civil case against 34-year-old Ronaldo, seeking damages of £165,000.
The Juventus star, who last week became one of only six players to score 700 career goals, met Ms Mayorga in June 2009 at Palms Casino Resort where she worked as a bar hostess.
The five-time Ballon d’Or winner had finished his Premier League-winning season for Manchester United prior to joining Real Madrid.
Ronaldo, who was on holiday with his brother-in-law and cousin, invited Ms Mayorga and her friends to his penthouse for a party.
Waiving her anonymity last year, she told German newspaper Der Spiegel that she was in the bathroom changing to go into the Jacuzzi when Ronaldo walked in exposing his manhood.
