The Las Vegas police department released the following statement:
"The Las Vegas Metropolitan Police Department responded to a call of a sexual assault on June 13, 2009.
"At the time the report was taken, the victim did not provide detectives with the location of the incident or suspect description. A medical exam was conducted.
"As of September 2018, the case has been reopened and our detectives are following up on information being provided by the victim.
"This is an on-going investigation and no further details will be released at this time."
The Portuguese player has been accused of raping Kathryn Mayorga on June 13 2009, which he has denied.
Mayorga went public with her allegations to Der Spiegel, in which she alleges that Ronaldo anally raped her, before apologizing and saying that he was "99% good, apart from the 1%."
Ronaldo called the allegations "fake news" in an Instagram post which he later deleted.
At the time of the alleged rape, Mayorga signed a settlement directly with Ronaldo's legal team which promised her $375,000 in exhange for her never again speaking about the alleged incident.
However, Mayorga's new legal team has submitted a complaint to overturn the settlement, alleging that she was traumatised at the time of the settlement being signed, and therefore the agreement was invalid.
The full complaint can be read on Der Spiegel's website here, which features Mayorga's full description of the alleged events that took place on the night of June 13 2009.
The sports editor of Der Spiegel, Christoph Winterbach, tweeted the following in response to Ronaldo's defence of "fake news".
