Nice-Matin reported six arrests, including the two suspected burglars, in a coordinated operation spanning the Alpes-Maritimes, Var, Hérault, and Doubs. Other reporting by AFP and RTL put that number at five.  That discrepancy remains in the published French accounts. RTL identified the investigating services as Nice’s interdepartmental judicial police service, the SIPJ, working alongside France’s specialist cultural property crime unit, the OCBC.  While the Marseille prosecutor’s office, which has taken over the investigation from Grasse, hasn't yet commented. 

This week's arrests offer a possible route towards establishing what happened after the burglars left the grounds, who else may have been involved, and where the missing paintings might have been taken. They do not yet establish the suspects’ guilt or resolve the loss.  For the Musée Renoir, the investigation’s most consequential development would be the recovery of the two works, with their condition assessed and their safety secured.
