French prosecutors have opened an investigation into aggravated public insult and incitement to hatred or violence after a Paraguay senator racially abused World Cup.

Axar.az reports that the Paris prosecutor’s office told The Associated Press on Tuesday that it launched the probe after the national unit for combating online hate received a complaint from the French Football Federation (FFF).

Celeste Amarilla, a senator from Paraguay’s Liberal Radical Party, posted racist comments on X after Mbappe converted the winning penalty in France’s victory over Paraguay on Saturday. She mocked the France captain’s origins, upbringing, education and appearance. France advanced to the quarterfinals where it will face Morocco on Thursday.

Mbappe called her a “despicable woman” who was “unworthy” of serving in Paraguay’s Congress.

The Paris prosecutor’s office said “the remarks were allegedly made because of the victim’s actual or perceived origin, ethnicity, nationality, race, or religion.” These offenses were punishable by up to one year of imprisonment and a 45,000 euros fine ($51,000).

Amarilla later issued an open letter in French and Spanish to Mbappe on social media, in which she said her problem was with the player, not the country of France. She wrote that she regretted mistreating Mbappe with “the same insults” she’s received as a mixed-race person and she had deleted her post.
