The fight itself is pretty wild, what with the real-life application of MMA maneuvers, but the participants put this over the top. Apparently, one of the gentlemen getting worked over in the stands is the father of not only the goalie trying to climb over the boards but also the referee trying to climb out of the rink. This is basically Slap Shot with an extra generation.

Here's some more context from Eurohockey.com, translating IJSHockey.com:

The final round robin match in the Larry van Wieren Cup had to be abandoned at the 45 minute mark after a brawl in the stands had broken out. According to IJshockey the atmosphere inside the arena had been unpleasent for some time and a hit finally set things off. The father of ref Ramon Sterkens and Eindhoven back-up goalkeeper Michael Sterkens was hit that set both of them off, Ramon tried to get off the ice to help his father, while Michael climbed up onto the glass. The NIJB gave the victory to Eindhoven who was leading 5:1 at the time. Both Eindhoven and Geleen will see each other in the Finals next weekend.

A personal favorite moment is when the guy refuses to open the rink door for the referee.
