It's not the first time Mayhem's lived up to his name ... he's got a (very long) rap sheet.
In 2011, Miller was arrested for allegedly putting his sister in a headlock ... and refusing to release her.
Then in 2012, he was arrested for allegedly going into a church and spraying a fire extinguisher, before getting buck naked.
In 2015, Jason was locked up for allegedly trying to use a ceramic tile as a weapon against cops ... before being tased and arrested.
During his day, Miller was a really good MMA fighter ... beating Robbie Lawler and Tim Kennedy, back in the day. Miller spent time in the UFC ... but last fought for the promotion in 2012. Mayhem hasn't fought anywhere professionally since 2016.
