West Ham United's 2-1 victory over Chelsea in the fourth round of the League Cup was marred by crowd trouble as missiles were thrown inside the London Stadium.
In the latter stages of the game with the Hammers two goals up, reports emerged that objects were thrown back and forth between the two sets of supporters.
A large steward presence was required as a standoff is said to have ensued, before police in riot gear arrived on the scene amid concerns that the situation could escalate.
Goals from Cheikhou Kouyate and Edimilson Fernandes secured West Ham's place in the quarter-finals of the competition, but the crowd unrest is expected to dominate the headlines surrounding the match.
