Impact Wrestling posted the following video, showing Ken Shamrock attacking the referee after the show went off the air.
In the clip, which you can see below, Shamrock continued to attack the ref after he, Sami Callihan, Chris Bey, and Moose lost a match to Trey Miguel, Willie Mack, Rich Swann, and Tommy Dreamer. Eventually, Callihan got Shamrock to break the hold. Ken then punched him and Shamrock reapplied the hold to the official. When other officials came into the ring, he attacked them as well.
