James Maddison had his sign - which read 'north London is WHITE' - confiscated at the World Darts Championship final on Wednesday night, according to reports.
Maddison watched on as Luke Littler's dream of becoming the world's youngest-ever darts champion was dashed after a breathtaking comeback by Luke Humphries, who won five straight sets to claim a 7-4 victory.
Despite the gripping drama on the oche, revellers made their own fun with anti-Tottenham chants.
A chorus of 'Tottenham get battered everywhere they go' was belted out around a raucous Alexandra Palace as footballing rivalry overspilled into the darts.
