26-year old Zachary Madsen has had at least one previous run-in with the law. He was arrested on January 5th in Lincoln, Nebraska and he was charged with stalking. No word on where things stand with that case.
According to his LinkedIn account, he has been working as a "contact center agent" for Allstate Financial Services since 2015.
WWE sources told us that Bret Hart was not injured. However, CBS reported that one security guard suffered a minor injury. There are reports that the man landed one punch on Hart before Travis Browne, Drake Maverick, Shane McMahon, The New Day, Dash Wilder, Davey Boy Smith and others swarmed the ring.
According to Madsen's Facebook account, he claims to be an amateur MMA fighter. Records show he has only participated in three low-level fights.
Madsen has been charged with 2 counts of 3rd-degree assault and trespassing.
