New footage has emerged showing West Ham midfielder Flynn Downes throwing punches after the Hammers' Europa Conference League semi-final win over AZ Alkmaar descended into utter carnage.
The Hammers secured a 1-0 win on the night after Pablo Fornals struck in injury time, taking them through to the final of the competition with a 3-1 win on aggregate.
However the historic result - which sees West Ham qualify for their first European final in 47 years - was marred by the abhorrent scenes that ensued afterwards.
A horde of violent Alkmaar fans, clad in all-black and hooded to hide their identities, forced their way into the away stands to trade blows with West Ham supporters at the final whistle.
