39 ultra-right members, including around twenty S members, were placed in police custody in Paris. They were arrested for "participation in a group with the aim of committing damage" Among them are well-known figures from the movement, including the former leader of the small group “Zouaves”, Marc de Cacqueray-Valmenier.

At least two of them were equipped with crutches, which could be considered weapons by destination, according to a source close to the case.
