A suspect is being held in custody after Amiens captain Prince Gouano complained of suffering racial abuse during Friday's Ligue 1 game at Dijon.
The goalless draw in Dijon was halted in the 78th minute as players from both sides stopped playing and headed towards the touchline after monkey chants were directed towards Gouano.
"An inquiry is ongoing and a person is currently in custody in the wake of these events. His custody will be extended tonight, to allow further investigation," Dijon prosecutor Eric Mathais said in a statement.
It was the latest in a string of incidents of racist abuse that have blighted football this season, and prompted FIFA president Gianni Infantino to urge football authorities across the world to take a "zero tolerance" stance on racism.
"It's over," Gouano said after the game was interrupted. "We're not playing on. I'm taking off my team-mates. We're going to the changing room."
"I heard monkey sounds..." Gouano told reporters afterwards. "I turned around and there indeed was a man who was looking in my direction and who was continuing (to make the noises)."
