Despite a heavy police presence, West Ham's EFL Cup with Chelsea was marred by crowd trouble, prompting seven arrests.
Police made seven arrests after crowd trouble marred West Ham's 2-1 win over Chelsea in the EFL Cup on Wednesday.
The fixture, typically played in a fraught atmosphere between London rivals, was subject to heavy stewarding and policing.
But problems developed late in the game, as stewards battled to maintain segregation between the two sets of fans with Chelsea 2-0 down.
A Metropolitan Police statement read: "Although the vast majority of people left the stadium peacefully and were well behaved, there were a minority of people who attended the match that were clearly intent on being involved in confrontation and violence.
