Videos on social media show a violent brawl erupt outside the Mudlark pub on Montague Close, London, just after 1pm on Saturday - ahead of Sunderland AFC and Millwall's EFL Championship fixture at The Den.
Large groups can be seen approaching the pub in the video, before surrounding the boozer.
The situation then escalated further and video footage showed fights break out involving multiple people, as reported by the Daily Star.
