Oh the mayhem!! TMZ reported that UFC fighter Jason “Mayhem” Miller was arrested last week for assault. But here’s the fun part…the assault charges came from his sister, whom he allegedly put into a head lock and then refused to let her go.

Just a little big bro lovin’ right? Apparently not, authorities told TMZ that Miller and his sister were at a house party in North Carolina, when she said she wanted to leave.

That’s when Mayhem, who obviously wanted to stay, allegedly wouldn’t let his sister leave and put her in head lock. Sounds a little over the top to me…Isn’t that what brothers and sisters do?!
