Overview
- On Monday Thomas Brail was the only person detained during a morning action at the Perrignier worksite and was taken into garde à vue at the gendarmerie of Bons‑en‑Chablais.
- Activists have spent about two and a half weeks using peaceful, physical positioning in front of Eiffage machines to stop tree felling, saying machines are required in practice to stop about 10 metres from people.
- Construction of the 16.5 km A412, which follows the D903 between Thonon‑les‑Bains and Machilly, began in early September after a change of prefect; work continues despite on‑site obstruction.
- France Nature Environnement, with 21 NGOs and 40 local residents, filed legal challenges on September 16 against the project and those judicial proceedings remain active.
- Brail is a high‑profile figure from the A69 campaign and founder of the Groupe national de surveillance des arbres, making his detention a notable escalation that could heighten national attention and affect tactics by both protesters and authorities.
