Semenyo’s case is the latest in a growing list of racist abuse suffered by Premier League players this season, with four players targeted during a single weekend in February.
The UK Football Policing Unit (UKFPU) is investigating the abuse of the four players in February, which included Sunderland defender Lutsharel Geertruida, Burnley midfielder Hannibal Mejbri, Chelsea defender Wesley Fofana and Wolves striker Tolu Arokodare.
Earlier on Monday, Sunderland condemned racist abuse directed at forward Brian Brobbey on social media following his side’s 1-0 league win over Tottenham.
