A 27-year-old accused was attacked at the Aix-Luynes penitentiary center. He has been on trial since last week at the Bouches-du-Rhône assizes for a triple homicide dating back to 2016.

His vital prognosis is not in jeopardy, but he was hospitalized under police surveillance. All three are suspected of being the authors of a dramatic settling of scores that occurred on April 2, 2016, in the Bassens city (Marseille, 15th century)
