Environmental activist Thomas Brail was arrested on Monday around 10:30 AM at the A412 highway construction site in Perrignier, Haute-Savoie. The arrest was confirmed by Arnaud, a local snail farmer and member of the Confédération paysanne, who was present at the scene. Brail was taken to the gendarmerie in Bons-en-Chablais and remained in custody through Monday afternoon. According to Arnaud, Brail was the only person from the activist group present at the time who was arrested, despite not seeking arrest or media attention. The protest actions against the A412 highway have been ongoing for about two and a half weeks. Activists have been staging "peaceful actions," positioning themselves in front of construction equipment from the company Eiffage to prevent the cutting down of trees. According to the rules in place, the construction machines are required to stop approximately 10 meters away from the activists. These efforts aim to slow the progress of the construction work, which has faced significant local opposition. The A412 highway is a 16.5-kilometer project that follows the route of the D903, intended to improve travel between Thonon-les-Bains and Machilly. Construction began in early September, shortly after the appointment of a new prefect on August 21, in a context marked by strong local resistance to the project. The new prefect's arrival and the start of construction have intensified concerns among residents and environmental groups. France Nature Environnement, an environmental organization, has raised alarms about the A412 project, comparing it to the controversial A69 highway. The organization, along with 21 other NGOs and 40 residents, filed multiple lawsuits against the project on September 16. They describe the A412 as an "unnatural project," citing environmental and social concerns. Their legal actions aim to challenge the project's legitimacy and halt its progress.
