Dagenham & Redbridge have asked police to investigate an allegation of racist abuse by a Rochdale player on Saturday.
Daggers defender Gavin Hoyte reported the alleged comment to referee Steve Rushton, who has included the incident in his report to the Football Association.
And a statement from the League Two club, who were holding an anti-racism event on the day of the game, confirmed the Metropolitan Police are now involved.

"Dagenham & Redbridge Football Club wish to reiterate that they have a zero tolerance stance on racism.
"No further statements will be made by the Club on this incident until all investigations have been completed by the appropriate authorities."
