Does a photo prove that climate activist Greta Thunberg was arrested in Rome for throwing confetti in a fountain at St. Peter's Square in October 2026? No, that's not true: That image of her had been online since 2023, and it showed her arrest in Sweden, not Italy. The rumor originated from a self-described satire network of pages known to produce made-up stories.
The claim appeared in a post (archived here and here) on X where it was published by @TodayUpdates0 on Oct. 24, 2026. It read:
Greta Thunberg was arrested again, but this time it's different. This time, she's not getting out. Thunberg 'crossed the line,' according to Interpol Director Josef Barrone. 'Setting off an explosive device, no matter how small, is an act of terrorism.' Thunberg was taken into custody by police in Rome after she threw an exploding box full of confetti into the fountain in St. Peter's Square. She faces a mandatory minimum of three years in prison. 'She's very lucky nobody was hurt, or it would be much longer.' Her parents paid her $5 million bail. What's your response to this......??👀 MAKE THIS GO VIRAL ON X. LET'S GO 👏
Here is what the image shared in the post looked like on X at the time of publication:

The post was published on the day when Europe saw a wave of youth protests across multiple cities, and that included (archived here) the Italian capital.
However, the claim about Thunberg's arrest was not true.
The first indicator that the story may not be real was the spelling of the word 'police' seen on the officer's uniform. Had the photo actually been taken in Rome, the identifying label would be Italian, reading 'polizia' -- not 'polis.' Additionally, St. Peter's Square is located in Vatican City, an independent state surrounded by Rome, not in Rome itself.
A reverse image search on TinEye (archived here) showed that the image had been online since July 6, 2023, when it was published, for example, by the Guardian (archived here). The article discussed Thunberg's arrest in the Swedish city of Malmö.
As seen in the photos capturing Swedish law enforcement on the Getty Images database (archived here), their uniforms read, "POLIS" -- just like in the image from the post reviewed in this fact check.
A search on Google News for the keywords "Greta Thunberg Rome Italy arrest" (archived here) did not show any reports from established media organizations corroborating the claim that the activist was arrested in the Italian capital in the first 10 months of 2026 -- or ever before that.
The post that is the focus of this fact check mentioned "Interpol Director Josef Barrone". As of publication, the Interpol website contained zero mentions of such a person (archived here). In October 2026, the president of the organization was Lucas Philippe of France (archived here), and Interpol's secretary general was Valdecy Urquiza of Brazil (archived here).
"Josef Barrone" was a derivative of the name "Joe Barron" frequently used in the fictional articles published by self-proclaimed liberal troll Christopher Blair and his allies who run the ALLOD network of pages and websites that show satire disclaimers everywhere.
Textual searches across social media led to an earlier post (archived here) making the same claim. It was published by the "America's Last Line of Defense" account on Facebook on Sept. 14, 2026.
The page's self-description (archived here) read:
The flagship of the ALLOD network of certified trollery and propaganda for cash.Nothing on this page is real.
Another variation of the claim about Thunberg's purported arrest in Rome (archived here) could be found on the SpaceXMania website where it was published on Oct. 22, 2026. In that article, the fictional "Interpol Director" was "Alex Bruno". The same name appeared in the supposed writer's byline.
The SpaceXMania website's "About us" tab (archived here) read:
We are a team of writers and editors based in New York, USA. Our mission? To bring you the freshest fake news, some sassy analysis, and a good dose of satire, all rolled into one crazy concoction that orbits around Elon Musk and everything that's lighting up the viral/trending charts.
In 2024, the New York Times (archived here) described SpaceXMania as a network that competes with that of Blair and relies on AI to produce its content. In an interview with the newspaper, Blair accused his rivals of plagiarism.
