Overview
- Masked intruders entered the Nyon residence on Tuesday, May 19, threatened occupants, forced a family member to open a safe and fled with its contents while Prost suffered a slight head injury.
- The public prosecutor in the canton of Vaud opened a criminal investigation and cantonal police mounted a large search using patrols, dog units and forensic teams with French authorities also involved.
- Swiss tabloids identified the household as belonging to four‑time F1 champion Alain Prost though prosecutors initially did not name the victims; Prost is reported to have returned to Dubai and his management has not commented.
- Coverage and industry sources say the attackers likely sought valuable watches, a pattern that mirrors a string of professionally organised thefts around Lake Geneva in recent months including at least 18 similar cases in 2025.
- Family members received on‑site care after the attack and investigators warn the professional methods and proximity to the French border make the probe complex and could extend the search for the suspects.
