This thread appears to have veered off on a bit of a tangent. As someone who was directly involved on Sunday, I would like to confirm that my description of events only refer to the incident I was involved in, as it appears there were several separate confrontations, involving both fans from inside the ground, and passers-by in cars.
As has been mentioned more than once it is all very unfortunate, and is playground stuff really. As luck would have it I will not be present at Sheffield united, or in fact any match until at least December, as I will be in Asia for a while. Hopefully when I return things will have cooled off and I will have regained my passion for following the team, a passion which is feeling more than a little deflated after this weekend.
