The Football Association will investigate allegations of racist abuse by a Manchester City supporter during Saturday’s derby at the Etihad Stadium.
A video circulating on social media appeared to show a fan aiming monkey chants towards Manchester United players during the Red Devils’ 2-1 victory.
City swiftly issued a statement saying the club was working with Greater Manchester Police and the FA was planning to talk to the clubs, referee Anthony Taylor, the police and other relevant parties.
A spokeswoman told the PA news agency: “We will be investigating.”
The police said on Saturday evening that no arrests had been made and enquires were ongoing.
PA understands United reported the incident to City and Taylor, with more than one of their players feeling they had abuse of a racist nature aimed at them.
There were also reports of missiles being thrown as tempers boiled over in the stands, with Fred appearing to be hit by an object hurled from the crowd as the visitors prepared to take a corner.
United boss Ole Gunnar Solskjaer said: “Fred and Jesse (Lingard) were in the corner, taking a corner, and I’ve seen the video, heard from the boys.
“We keep talking about it every bloody week. But he’s been caught on camera. He should, in my opinion, never be allowed into a football ground again and I’ve seen the video. Unacceptable.”
City’s statement read: “Manchester City FC are aware of a video circulating on social media which appears to show a supporter making racial gestures during the second half of the match against Manchester United this evening.
“Officials from the club are working with Greater Manchester Police in order to help them identify any individuals concerned and assist with their enquiries.
“The club are also working with GMP regarding an instance of objects being thrown onto the field of play.
“The club operates a zero tolerance policy regarding discrimination of any kind, and anyone found guilty of racial abuse will be banned from the club for life.”
