Video: West Ham United fans 'caught fighting each other after Sunderland match'

A video has emerged appearing to show West Ham United fans involved in a brawl with one another following last Saturday's Premier League match against Sunderland at Upton Park.

The unsavoury scenes, which also shows a police officer getting pushed by a fan, were filmed and uploaded onto YouTube following the Hammers' late 1-0 win over the Black Cats.

According to 101greatgoals.com, the West Ham fans turned on each other outside the ground after the final whistle last weekend.

The reasons behind the punch-up are unclear.
