This video, posted on Monday by YouTube user jmurr1988, shows a hockey parent slapping the glass following some on ice action. The parent stands up, approaches the ice, and puts his hand through the plexiglass.
There's not much information about the video aside from what we can observe, but you can take a look for yourself and see the incident take place.
Following the glass breaking, the parent points out on to the ice and yells a bit more before he appears to leave. We hope the glass could be replaced and these kids got to finish their game.
