A Chelsea fan was reportedly arrested for allegedly racially abusing Tottenham player Heung-min Son.
The Guardian report that a supporter was ejected from the Tottenham Hotspur Stadium and arrested for committing a racially aggravated public order offence.
It is understood the incident was reported by fellow Chelsea fans.
Blues defender Antonio Rudiger was also subjected to alleged racial abuse from Spurs fans on Sunday afternoon.
He signalled towards his captain Cesar Azpilicueta and referee Anthony Taylor that monkey chants were being directed at him.
It came after Son was sent off for a kick out at Rudiger.

Soon after the defender reported the abuse, Taylor implemented the first step of FIFA’s protocol in dealing with discrimination in games – with a stadium announcement stating that ‘racist behaviour is interfering with the game.’
Two further calls from the stadium PA came before the end of the contest, which Chelsea won 2-0.
Tottenham released a statement on Monday vowing to ‘exhaustively’ investigate the matter involving Rudiger.
The statement read: “During yesterday’s match against Chelsea, Antonio Rudiger reported hearing alleged racist abuse from an individual(s) in the South Stand.
“We are able to track every fan via the cameras and have spent many hours reviewing CCTV footage. We have engaged lip readers to study the footage and contacted Chelsea for further information from their players. We have also taken statements from other parties present at the time. The police will be reviewing our evidence alongside us. Please be assured we shall be exhaustively investigating this matter.
“This club has a proud track record of anti-racism work across all our communities and we are determined to ensure that we conduct a thorough investigation. Any fan found to be guilty will receive a lifetime ban. At this time however we should point out that our findings are inconclusive and would ask that comment is reserved until the facts are established.

“If anyone has any further information they should please email email@example.com or text 07537 404821.
“In respect of protocols – when the incident was conveyed to the referee Anthony Taylor, he took the decision to call for the implementation of Stage 1 of the UEFA protocol – rather than the Premier League protocol – and asked for an announcement to be made, as well as requesting a further announcement which created a misconception that any issue was on-going. The Premier League protocol differs from UEFA protocol in that it does not call for an announcement rather that the individual(s) be dealt with by the Safety Team in the first instance.
“We have asked that the Premier League clarifies the position regarding the use of these protocols to all stakeholders going forward.”
