Arsenal fans have reportedly damaged signs at White Hart Lane after their victory over rivals Tottenham on Wednesday night.
The Gunners' players covered themselves in glory to progress to the fourth round of the Capital One Cup but the club's supporters did not.
Minor scuffles between fans and stewards are believed to have taken place after the final whistle as parts of signage that adorn the stadium were ripped out of position.
Photographs appeared to show Arsenal fans revelling in the damage and goading Tottenham supporters that were housed in lower sections of the ground.
The Gunners have been handed a trip to face Sheffield Wednesday in the next round of the competition.
Spurs, meanwhile, will have to focus on either the FA Cup or Europa league if they are to claim a trophy from a knock out competition this season.
