(CNN) A woman has accused Cristiano Ronaldo, one of the world's biggest soccer stars, of raping her in a Las Vegas hotel room in 2009.

Kathryn Mayorga says the Portuguese footballer, who plays for Italian club Juventus, raped her while she repeatedly screamed no, according to a lawsuit filed Friday in Clark County, Nevada.

After the attack, according to the lawsuit, Ronaldo apologized, "stating he was sorry, he was usually a gentleman." The lawsuit alleges that Ronaldo told his representatives that "she said 'no' and 'stop' several times."

Mayorga's lawsuit accuses Ronaldo, 33, and his team of taking advantage of her fragile emotional state to coerce her into signing a settlement and nondisclosure agreement in 2009. She claims she received $375,000 in exchange for her silence. Her lawsuit seeks to void the settlement and agreement.

Las Vegas police said Monday they had reopened the criminal investigation last month.

Ronaldo and Kathryn Mayorga met at Las Vegas' Rain nightclub, the lawsuit says.

Ronaldo's representatives denied the rape allegations when German publication Der Spiegel first reported them in 2017. After the outlet broke news of the lawsuit Friday in an interview with Mayorga, Ronaldo's lawyer called the reporting "blatantly illegal."

"It violates the personal rights of our client Cristiano Ronaldo in an exceptionally serious way. This is an inadmissible reporting of suspicions in the area of privacy," lawyer Christian Schertz said in a statement.

Ronaldo appeared to dispute the claims in an Instagram live post Friday: "What they said today, fake -- fake news. They want to promote by my name. It's normal. They want to be famous -- to say my name. Yeah but it's part of the job. I'm (a) happy man and all, all good."

Reached by CNN on Sunday, Mayorga's attorney, Leslie Stovall, declined an interview request. But Stovall released a statement Monday in response to Ronaldo's Instagram post.

He said the complaint, the physical evidence, Ronaldo's alleged answers to questions about the assault, the circumstances of the settlement and Mayorga's "psychological injuries" are not fake news.

His client is seeking justice, he said, to hold the soccer star accountable, to protect other women, to demonstrate how "fixers" enable sexual assault and to convince victims to pursue charges against alleged perpetrators, "no matter how wealthy, famous or powerful they may appear to be.

The alleged attack

Mayorga met Ronaldo at the now-closed Rain nightclub, inside the Palms Hotel and Casino on June 13, 2009, the complaint says. Ronaldo invited her, her friend and others to his penthouse suite. According to Mayorga's lawsuit, Ronaldo asked her to join the group in a hot tub and gave her shorts and a T-shirt to wear.

As Mayorga changed in a bathroom, she said Ronaldo approached her, exposed himself and asked her for oral sex. Mayorga said she refused, but that Ronaldo pulled her into a bedroom and raped her as she screamed, "No, no, no."

The same day, she reported the incident to police and went to the hospital for a sexual assault examination, the lawsuit says.

Ronaldo joined Italy's Juventus this summer after nine seasons with Real Madrid.

Initially, she refused to identify Ronaldo to police, fearing public humiliation, her complaint says. Weeks later, when she named him in a police interview, a detective told her that she would be subjected to retaliation and her actions portrayed as extortion attempts, according to the lawsuit. A nurse who examined her said the same thing, she says in the lawsuit.

"The psychological trauma of the sexual assault, the fear of public humiliation and retaliation and the reiteration of those fears by law enforcement and medical providers left plaintiff terrified and unable to act or advocate for herself," the lawsuit claims.

Meanwhile, Ronaldo retained a team of "fixers" that the lawsuit calls "personal reputation protection specialists" and are unnamed defendants. The lawsuit alleges they monitored Mayorga, her friends and family, and law enforcement to "develop and implement a strategy" to prevent or delay public disclosure of the allegations and criminal prosecution of Ronaldo. The team communicated with Mayorga's lawyer at the time, who agreed to private mediation with them. Mayorga's lawyer did not follow up with Las Vegas police, according to the lawsuit.

According to Las Vegas Metropolitan Police Department spokesman Aden Ocampo-Gomez, Mayorga did not provide an assailant's name or location of the alleged assault in her 2009 complaint. She wanted only to report a sexual assault and submit to a medical exam, he said.

Investigators did not follow up with Mayorga and the case was closed shortly thereafter, he said. But the evidence, including images and other information from the exam, is still with police. The case is being reopened at the request of Mayorga or someone representing her, Ocampo-Gomez said.

The settlement

The lawsuit accuses Ronaldo of battery for sodomizing her. Additional claims against him and his representatives include intentional infliction of emotional distress, coercion and fraud, and abuse of a vulnerable person.

In mediation discussions, Ronaldo's representatives led her to believe they were attempting to compensate her for her injuries, and that agreeing to the settlement precluded her from cooperating with police. In reality, the lawsuit claims, his team was attempting to obstruct a criminal investigation and erode Mayorga's credibility, thus diminishing her chances of pursuing a claim for civil damages. The allegations form the basis of Mayorga's claims of coercion and fraud, racketeering and civil conspiracy, and abuse of process.

Her family, who lives in Las Vegas, attended mediation to provide her with emotional support and advice. But Ronaldo's team and the mediator excluded them from talks, according to the lawsuit.

Knowing she was a "vulnerable person," Ronaldo's team reinforced the threat of public humiliation if anyone publicly disclosed her allegations or cooperated with law enforcement, her complaint says. They threatened to portray her as having consented to sex and then making a false claim so she could extort Ronaldo for money.

Mayorga described mediation "as re-experiencing the sexual assault," an ordeal marked by "extreme fearfulness, complete helplessness and eventually a sense of passivity where she would do anything just to be able to leave/escape/avoid revisiting the sexual assault by continuing the mediation," the lawsuit says.

The aftermath

Over the years that Mayorga maintained her silence, her emotional health suffered under the weight of post-traumatic stress disorder, according to the lawsuit. She says she struggled to maintain relationships or hold down a job.

Then, a sports website leaked copies of documents and communications between Ronaldo and his team relevant to the mediation to Der Spiegel, which published a detailed account of the allegations in April 2017. Mayorga retained legal counsel, fearful that she might somehow be linked to the article and deemed in violation of the settlement, one of her lawyers, Larissa Drohobyczer, told CNN. Motivated by the #MeToo movement, she decided to come out publicly and move forward with the lawsuit after her team obtained corroboration of her account, Drohobyczer said.

One of the purported documents, quoted in the lawsuit, calls the settlement "incredibly favorable" given the nature of Mayorga's claims and the potential impact they could have on his personal and professional reputation, including endorsement opportunities. And, the document says, it avoided the potentially "catastrophic effect" of not letting him travel in the United States.

Ronaldo's representatives forcefully denied Der Spiegel's account and threatened legal action against the publication. They called the account a "journalistic fiction" that contained "unattributable and unsubstantiated allegations" that were "untruthful and false," according to the lawsuit. Their denials form the defamation claims in Mayorga's lawsuit.

Mayorga did not participate in the article and was not named in it. In a later interview published by Der Spiegel on Saturday, in which she was identified for the first time, she said that she had followed the online reaction to the original story closely. She had taken notice of comments about the athlete's desirability, she told the magazine, including statements to the effect of, "As if Ronaldo even needs to rape a woman."

Those statements mirrored thoughts she once had about Ronaldo, she told the magazine. But she wasn't going to be silent any more.

Ronaldo has been considered one of the world's best -- if not the best -- player for a decade. He's played for the top clubs, including Spain's Real Madrid and England's Manchester United, and joined Juventus this summer for a reported $117 million transfer fee.

He won 2017's Ballon d'Or, given to the best male player in the world. It marked his fifth time hoisting the trophy, a feat matched only by Argentina/Barcelona star Lionel Messi. He counts a lifetime Nike deal among his many endorsements. The father of four is also well-known for his philanthropy, especially when it comes to children's causes.

Last year, Ronaldo ran afoul of Spanish authorities, who accused him of tax evasion. He settled the case in June, paying a $21.8 million fine, according to Spanish newspaper El Mundo.
