“We noticed practically everything there was to see,” Sports Minister Amélie Oudéa-Castera told France 2 television, referring to images of Lyon coach Fabio Grosso bloodied after being hit in the face and skull by shards of glass.
The visiting team’s bus was riddled with rocks and beer bottles as it headed to Marseille’s Velodrome Stadium on Sunday.
Oudea-Castera said fans also chanted homophobic and racist slurs at the stadium.
“It’s painful, disgusting and disgusting,” he said.
Interior Minister Gerald Darmanin said nine other people had been arrested so far.
“I hope that the harshest penalties will be imposed on the enthusiasts who ruined everyone,” he told BFM TV.
Possible sanctions on clubs would depend on football authorities, but as the attacks took place outside the stadium, the French League (LFP) does not have the competence to sanction the home team.
Their rivals, Olympique Lyonnais and Olympique de Marseille, have a history of violence between fans.
In a statement, the Lyon team “regrets that such situations occur every year in Marseille and calls on the government to assess the severity and repetition of such incidents before an even more serious tragedy occurs. “
“What happened to Fabio Grosso is absolutely unacceptable,” OM President Pablo Longoria said.
“It’s something that can’t happen in football. Even if it happens outside the stadium, it’s unacceptable. I’m angry and appalled by the situation. “
Two years ago, Ligue 1 was marred by several acts of violence and riots among the public.
Darmanin denied that the government had been prepared for the threat of violence in Marseille over the weekend and said 500 police officers were present.
On Monday, he said he was pleased with the security scenario surrounding the Rugby World Cup, which ended on Sunday and for which he said some 13,000 members of the security forces were deployed each day.
He said France would deploy ten times more resources to ensure security around next summer’s Olympics.
Some matches of the Olympic opening will be played in Marseille.
