Ronaldo's lawyer, Peter S. Christiansen in Las Vegas, downplayed the development and denied a Nevada woman's allegation that Ronaldo raped her in Las Vegas in 2009. The lawyer says sex was consensual and evidence collection is standard practice.
A police sexual assault investigation was closed in 2009 but reopened last August, before the woman filed a civil lawsuit in Nevada claiming that Ronaldo raped her.
Cristiano Ronaldo's lawyer says U.S. investigators are seeking DNA from Cristiano Ronaldo in their investigation of a Nevada woman's allegation that the international soccer star raped her in his Las Vegas hotel penthouse in 2009.

It was closed in 2009 but reopened days before the woman filed a civil lawsuit in Nevada in September claiming that Ronaldo raped her.
