Multiple reports say only that suspicious temperature anomalies were recorded and that Météo-France filed a complaint. They do not confirm that a specific person "walked up to the probe" or that a portable heater was actually used.

• Euronews says: "Online rumors, which remain unverified for the time being, claim the temperature reading was manipulated by someone using a hair dryer to generate a higher temperature." That directly contradicts stating the heating method as settled fact.
• Le Parisien / AFP reports that Météo-France filed a complaint after physical findings and sensor-data analysis, but also says Météo-France did not directly link its complaint to the reports about Polymarket and that the Bobigny prosecutor had "no element to communicate at this stage" because the investigation was only beginning.

So the reliable, sourced version is: there were suspicious spikes and an investigation/complaint — not a confirmed account of a person heating the probe with a portable device.

The post overstates the legal step taken by Météo-France.

According to Le Parisien / AFP, Météo-France said it "déposé plainte" — i.e. it filed a complaint — for tampering with an automated data-processing system. The same report says the Bobigny prosecutor had no details to communicate yet because the investigation was only beginning. Euronews likewise says Météo-France filed a complaint with the Roissy air transport gendarmerie brigade.

That is not the same thing as Météo-France itself having already filed criminal charges. A complaint had been lodged; charges had not been publicly announced at that stage.
