Police in riot gear were forced to intervene after a large group of Manchester United supporters cornered visiting Brentford fans outside Old Trafford last night.
Video footage showed both stewards and officers from Greater Manchester Police (GMP) with protective headgear step in as punches and missiles, including a smoke canister and piece of wood, were thrown at the entrance to the away end.
United supporters, via the medium of song, also wished death upon owner Joel Glazer, while some staged a walkout in the 73rd minute of the game. Before the match a larger number of supporters staged another protest on the forecourt to the east of the stadium, following similar gathering ahead of the games against Norwich City and Chelsea.
