Hundreds of opposing fans fought an on-pitch battle in the aftermath of Celtic's 1–0 victory in the 1980 Scottish Cup Final at Hampden, fuelled by alcohol and armed with the cans and bottles.[44][2][45] Despite previous instances of similar behaviour – less widespread and more speedily quelled, but still resulting in dozens of arrests – at the end of the 1965 Scottish League Cup Final,[46] 1969 Scottish Cup Final[47] and 1977 Scottish Cup Final[48] between the same teams at the same venue, a senior police officer on duty at the time estimated the number of his colleagues inside the stadium in 1980 was barely into double figures, with almost all the estimated 400 police outside Hampden dealing with expected disorder issues, and perimeter fencing assumed sufficient to keep the fans off the pitch.[44] This remains one of the worst invasions onto a football pitch ever reported, and was instrumental in alcohol being banned from all football grounds in Scotland, a situation which was still in place 40 years on.[29][44][49][50]
