Paris Saint-Germain’s home Champions League game against Istanbul Basaksehir has been suspended after an alleged incident of racism involving the fourth official.
PSG said players from both sides left the pitch in the 23rd minute during their final Group H fixture in Paris.
Players from the Turkish team were incensed, saying fourth official Sebastian Coltescu of Romania had used a racist term against assistant coach Pierre Webo, who is from Cameroon, before he was sent off with a red card at Parc des Princes.
Match referee Ovidiu Hategan of Romania had shown Webo the red card.
Basaksehir substitute Demba Ba demanded that the fourth official – Sebastian Coltescu of Romania – explain himself, while PSG players Neymar and Kylian Mbappe also demanded an explanation.
Basaksehir coach Okan Buruk said “you are racist” to Coltescu.
“After a red card is given by the referee to a member of opposition staff, discussions continue between players and staff of both teams with the referee,” PSG said on Twitter.
“The Basaksehir players decide to go back to the locker room, the Parisians follow them.”
Basaksehir posted a message on their Twitter account which read: “NO TO RACISM #Respect.”
The score was 0-0 when the incident took place about 15 minutes into the match.
