Arsenal launch investigation into alleged racist abuse of Kalidou Koulibaly

The club have issued a statement

Arsenal FC have launched an investigation into the alleged racist abuse of Kalidou Koulibaly by an Arsenal fan during their home tie against Napoli in the Europa League on Thursday night. A video circulated on social media, appearing to show an Arsenal fan using the N word to describe the Senegalese Napoli defender. An Arsenal statement declared: "We utterly condemn use of this type of racist language and have launched an investigation to identify the culprit. “We operate a zero tolerance approach, and anyone behaving like this is not welcome at Arsenal and will be banned from matches. “We have an extremely diverse community of fans who are all part of the Arsenal family and such incidents are rare at Emirates Stadium. “We encourage supporters to report any incidents as they happen to stewards or via our matchday alert service." This incident occurred on the same day that a video of Chelsea fans singing a bigoted chant about Mohamed Salah was posted to Twitter, prompting both Liverpool and Chelsea to issue statements condemning the chants and committing to identify any individuals responsible.
