French prosecutors opened an investigation into an online harassment complaint made by Olympic boxing champion Imane Khelif after a torrent of criticism and false claims about her sex during the Summer Games, the Paris prosecutor’s office said Wednesday.

The athlete’s lawyer Nabil Boudi filed a legal complaint Friday with a special unit in the Paris prosecutor’s office that combats online hate speech.

Boudi said the boxer was targeted by a “misogynist, racist and sexist campaign” as she won gold in the women’s welterweight division, becoming a hero in her native Algeria and bringing global attention to women’s boxing.

The prosecutor’s office said it had received the complaint and its Office for the Fight against Crimes against Humanity and Hate Crime had opened an investigation on charges of “cyber harassment based on gender, public insults based on gender, public incitement to discrimination and public insults on the basis of origin.”

Khelif was thrust into a worldwide clash over gender identity and regulation in sports after her first fight in Paris, when Italian opponent Angela Carini pulled out just seconds into the match, citing pain from opening punches.

Claims that Khelif was transgender or a man erupted online. The International Olympic Committee defended her and denounced those peddling misinformation. Khelif said that the spread of misconceptions about her “harms human dignity.”

Among those who referred to Khelif as a man in critical online posts were Donald Trump and J. K. Rowling. Tech billionaire Elon Musk re-posted a comment calling Khelif a man.

Khelif’s legal complaint was filed against “X,” instead of a specific perpetrator, a common formulation under French law that leaves it up to investigators to determine which person or organization may have been at fault.

The Paris prosecutor’s office didn’t name specific suspects.

The development came after Khelif returned to Algeria, where she met with President Abdelmadjid Tebboune on Wednesday and will be welcomed by family later this week in her hometown of Ain Mesbah.

In Algeria, Khelif’s former coach Mustapha Bensaou said the boxer’s complaint in France was initiated by the Algerian authorities and should “serve as a lesson in defending the rights and honor (of athletes) in Algeria and around the world.”

“All those involved will be prosecuted for violating Imane’s dignity and honor,” Bensaou said in an interview with The Associated Press. He added: “The attacks on Imane were designed to break her and undermine her morale. Thank God, she triumphed.”

The investigation is one of several underway by France’s hate crimes unit that are connected to the Olympics.

It is also investigating alleged death threats and cyberbullying against Kirsty Burrows, an official in charge of the IOC’s unit for safeguarding and mental health, after she defended Khelif during a news conference in Paris. Under French law, the crimes, if proven, carry prison sentences that range from two to five years and fines ranging from 30,000 to 45,000 euros.

The unit is also examining complaints over death threats, harassment or other abuse targeting six people involved in the Games’ opening ceremony, including its director Thomas Jolly.
