An investigation into intentional violence in a meeting with premeditation was opened after the stone-throwing of the Olympique Lyonnais bus on Sunday evening before the canceled match against Marseille, facts which caused “a serious injury” to Lyon coach Fabio Grosso, the Marseille prosecutor said on Monday.

This attack, for which the Italian coach of OL was granted an ITT (total incapacity for work) of 30 days, is punishable by ten years of imprisonment, specified the public prosecutor of Marseille, Nicolas Bessone, during a press briefing.
