During a video captured by an onlooking fan, an Oilers security guard can be seen acting very agressive towards a young fan and his father, even rushing back down the stairs in an attempt to fight one or both of them.
The man could be heard swearing at the young fan, and if that wasn't already bad enough, appeared to be attempting a physical altercation with him. The security guard was rightly removed from the game as a result of this altercation.
No matter the situation, it is very unusual for a security guard for a professional sports team to act in such an innapropriate way, and the Oilers are sure to deal with this issue internally and quietly, as to not take the attention of fans away from the ice.
