This flashpoint represents the climax of growing hostility between the fanbase and the organisation over recent months. A previous appeal for calm was issued in December following an incident that left a police officer with serious injuries.
The club explained: "For several months, despite the club's willingness to dialogue, we have been witnessing an escalation of violent and inappropriate behaviour. After the match against Laval, the red line was crossed. Individuals, some hooded and equipped with makeshift weapons, broke into the Centre de Vie Raymond Kopa to wait for the players. The arrival of law enforcement was necessary to prevent the situation from getting out of control."
