A scary scene unfolded this weekend at the Glory 42 kickboxing event in Paris, as fans responded to a brutal -- and controversial -- knockout blow.
It all started when Murthel Groenhart approached Harut Grigorian, who was turned around while stunned from a kick to the head, and delivered a devastating punch from behind. Grigorian immediately fell limp to the ground, and chaos ensued.
A swarm of angry fans would then storm the ring and assault Groenhart. Fortunately, he was able to escape fairly unscathed.
