The unidentified guy attempted to tackle bandmember Killer Mike at the Spotify House show and had to be hauled away by security guards.
Mike's sidekick El-P addressed the furore on Twitter.com, writing, "Thanks to everyone who watched us rock the @Spotify house! Sorry for the brief interruption... Shout out (to) our dudes... for holding us the f**k down."
Now, gig promoter Matt Sonzala has opened up about the drama, telling Buzzfeed.com the stage invader was not arrested and he's still "walking around downtown Austin talking to himself".
Sonzala adds, "After he was thrown out, I walked out and asked police working the line to get in if they planned on arresting the man who just attempted to assault the band onstage. They come with me and we find him right around the corner from the venue - he's sitting on a stoop, skull open, bleeding down his face. Police talk to him, come back and say to me they can't arrest him based on my testimony alone.
"They (police officers) claimed Run The Jewels owed him money and stole his lyrics."
