A Le Havre fan has been arrested by police for shouting racist insults to Ghana defender John Mensah in Olympique Lyon's 3-1 home win against the bottom club on Sunday."Around the 55th minute, a so-called Le Havre fan has been arrested by police because he had been shouting racist insults to John Mensah," Lyon president Michel Aulas told reporters. "It started during the warm-up and it went on during the whole first half." Coach Claude Puel added: "John was shocked. He heard some scandalous words." Mensah was sent off for a second bookable offence 20 minutes from time and Puel said he should have replaced him because the player was too upset to play. "It's my fault, I should have substituted him before," he said.
