I was there that day and my overriding memory is of a mass brawl that took place on the concourse of the Holte at half time, Villa v Villa. Everyone was angry and frustrated and the atmosphere down there was toxic. In the end, everyone turned on the police and I think a couple of them got quite badly hurt. I have no idea what kicked it all off and I didn't hang around down there (I was only about 13). I've never seen anything like it before or since.
I believe it was Ken McNaught who was forced off first, due to a bad tackle.
