Marseille hooligans overwhelmed security and stormed the pitch to take on home fans as tensions grew in their goalless draw at Angers.
Supporters climbed over the barriers and charged home fans behind goals in another tasteless night for French football.
The stewards and the stadium announcer tried their best to defuse the situation, but the furious crowd pushed them aside.
Supporters reportedly fired flares and firecrackers at each other during a Ligue 1 game, which saw Marseille in the second draw with Angers in third.
Reports in France even said Marseille had raised concerns before kick-off that it would be too easy for fans to reach the pitch at the Stade Raymond Copa.
And any anxiety well manifested when the chaotic scenes unfolded.
The latest controversy comes in the wake of crowd trouble at a host of Ligue 1 clubs.
Lens v Lillee had to be put on hold as home side militants stormed the pitch, while a Lillee fan faced a year in prison and a £13,000 fine after allegedly masturbating on the hosts.
At least 16 Bordeaux fans were injured after Montpellier fans were allegedly ambushed on the way to their league clash.
And last month Marseille were involved in another night of violence, when their league clash with Nice had to be called off after riots broke out on the pitch.
The match had to be abandoned as Nice fans reacted furiously when Dimitri Payet of Marseille threw a bottle thrown back at home fans.
This was followed by a major scuffle with Marseille coach Pablo Hernandez, even after a Nice fan was punched to the ground.
