Police say they are investigating after an FA Cup match between Haringey Borough and Yeovil Town was abandoned amid reports of racial abuse by fans.
Officers are also investigating after items were reportedly thrown onto the playing area, a Metropolitan Police spokesperson told BBC Sport.
Saturday's match was abandoned after Haringey's manager took his team off the field in the second half.
There have been no arrests yet and inquiries are continuing.
The match, played at Haringey's Coles Park Stadium, was in the fourth qualifying round of the FA Cup, with the winner set to progress to the first round proper.
Haringey goalkeeper Valery Douglas Pajetat was reportedly spat at and hit by an object thrown from the Yeovil Town end.
Defender Coby Rowe was then "racially abused", according to Haringey boss Tom Loizou, who said "there was no way I could let him continue".
