::I have found two references on the BBC website after a very simple search: 
 :::"A wave of hooliganism, with the Heysel incident of 1985 perhaps the most sickening episode, was justification enough for many who wanted to see football fans closely controlled. ... The 1989 image of football fans as scum - anti-social, violent young men who'd drunk too much - perhaps goes some way to explain the egregious behaviour of some of the emergency services and others after Hillsborough."  
 :::"The prime minister was informed that a senior member of the Merseyside Police directly blamed supporters: "One officer, born and bred in Liverpool, said that he was deeply ashamed to say that it was drunken Liverpool fans who had caused this disaster, just as they had caused the deaths at Heysel.""  
 ::I am sure there are many more if one takes the time to look further.
