Play was halted during the Liverpool versus AFC Bournemouth match at Anfield after Bournemouth forward Antoine Semenyo reported being racially abused by a supporter.
Match referee Anthony Taylor stopped the game in the 29th minute, consulting with managers and captains, with police officers later entering the referee's room at half-time.
The Premier League confirmed it would launch a full investigation into the incident, stating the temporary pause was in line with its on-field anti-discrimination protocol.
Sky Sports co-commentator Gary Neville expressed dismay, highlighting the incident as overshadowing the match and a 'sorry state' of affairs.
Despite the incident, Semenyo scored two goals for Bournemouth, though Liverpool ultimately secured a 4-2 victory.
