Gunners have launched an investigation into the vile social media video and released a statement 'utterly condemning' the supporter
A SICK Arsenal fan was caught on film calling Napoli star Kalidou Koulibaly "a f***ing n****r" during the Gunners' Europa League game against the Italian side.
In a video shot during the game, the troll can be heard using the N-word to refer to the Senegal international - with the slur also also written across the short clip.
The North London club have now launched an investigation after the clip was posted to social media following the 2-0 win over Napoli in the quarter-final first-leg.
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."
Koulibaly was also targeted with monkey noises during Napoli's defeat at Inter Milan in Serie A in December.
The centre-back hit back at supporters by insisting he is "proud of (my) skin colour" which soon sparked a huge campaign of support in Italy.
The latest shameful incident occurred on a night of embarrassment for English football, with Chelsea fans filmed chanting about Mo Salah being a "bomber".
A trio of Blues supporters where banned by the Stamford Bridge club from Slavia Prague's stadium before Liverpool also released a strongly-worded statement.
