I went on Wikipedia and I got a few instances of violence in the NHL...
Quote:
1982 - Jimmy Mann of the Winnipeg Jets left the bench and hit Pittsburgh Penguin Paul Gardner, breaking Gardner's jaw in two places. Police charged Mann, who was fined $500 and given a suspended sentence in Winnipeg.
1988 - Dino Ciccarelli hit Leafs defenceman Luke Richardson with his stick. Charged and convicted of assault, he is sentenced to one day in jail and fined $1,000.
These were the only two from the 80s. There's one from the 90s, but it's from 1998.
I hope that helps.
