West Ham United and the Metropolitan Police have launched an investigation after video surfaced of a West Ham United fan spewing anti-Muslim abuse at Liverpool star Mohamed Salah.

One of the incidents, filmed during the 1-1 draw in the Premier League on Monday, occurred as Salah was about to take a corner kick.

"We are aware of a video in which it appears racial abuse is being directed at a player at a West Ham vs. Liverpool game at London Stadium on Monday, Feb. 2," Metropolitan Police said in a statement issued to ESPN FC. "Officers are in the process of reviewing the footage.

"No arrests have been made and enquiries continue. Anyone who witnesses inappropriate behaviour during a match is urged to bring it to the attention of a steward or police officer."
