Former Manchester City and Liverpool striker asked if racism was legal in France on Saturday night after the Nice striker was subjected to monkey chants from Bastia fans.
Balotelli slammed the French league after Friday night’s 1-1 draw for not reacting quickly enough to the abuse, with an investigation now opened into the horrible scenes.
“Is it normal that Bastia supporters make monkey noise [and] ‘uh’ ‘uh’ for the whole game and no-one of the ‘commissions discipline’ say nothing?” Balotelli wrote, referencing the French league’s disciplinary committee.
“So is racism legal in France? Or only in Bastia? Football is an amazing sport. Those people like Bastia supporters make it horrible.”
Bastia responded to Balotelli’s accusations, saying: “Having not been informed at any stage, whether from the officials, the delegates or any member of Nice about an incident of this type, it is with astonishment that our club discovered these accusations.”
However, they added that it remains at the league’s disposal “so that all light is shed” on “this type of behaviour, which is by nature stupid and unacceptable.”
Nice backed their striker, saying: “Nice, which already had stones thrown at its bus before the game, is outraged by what happened to its players on Friday night and in particular to Mario Balotelli.”
Bastia were docked two points in the 2007-08 season after fans racially abused a Libourne St Serin player.
