There was a lot of violence before and during the match before the disaster. The disaster itself was caused by inadequate policing and the wall collapsing - both Belgium police and officials were successfully prosecuted.

Michael Baines, Stanley Conroy, Gary Cooper, Gary Evans, Kerin Hughes, Graham Postlethwaite, Gary Rutter, Timothy Williams, Terence Wilson, Alan Woodray, Mark Woods, Paul Wright, Ronald O'Brien and John Davies.
