The president of France's Professional Football League (LFP), Frederic Thiriez, has called for an investigation into claims Auxerre's Kamel Chafni was racially abused by a linesman. Chafni, a Morocco international, was sent off following an altercation with the assistant referee, Johann Perruaux, in the 55th minute of Auxerre's 1-0 loss at Brest in the French top flight on Saturday. The midfielder had to be restrained by his team-mates, as well as players from Brest, and as he left the pitch, following a delay of five minutes, he told television cameras he had been the victim of racist abuse. Moroccan Chafni claimed assistant referee Johann Perruaux told him “get lost, Arab”. Chafni reported it to referee Tony Chapron, but was booked and then sent off. "There is a foul that is not sanctioned, I got to the assistant referee to tell him it's not normal. He answers: 'get lost, Arab’. I go to the centre referee and I tell him what happened and he gives me a yellow card. I tell him it is unacceptable and he shows me a red card", Chafni told L'Equipe. Bourgoin also claimed that players from Brest had verified Chafni's version of events, but Chapron later insisted that there had been no racist remarks made by Perruaux. "I refute any accusation concerning these words. I know him too well for him to have said these words", said Chapron.
