A viral video on X captured a man savagely beating a woman at a Rüfüs Du Sol concert at the Rose Bowl on Sunday night.

The festival-focused social channel Festive Owl posted a video showing a man repeatedly punching someone. A woman who originally posted the video of the assailant noted that the cause of the disturbance was a drink being accidentally spilled. She then noted the man punched her in the face and knocked her out.

An Arizona woman who did not want to be identified is recovering after a brutal beating over the weekend at a sold-out concert in Pasadena’s Rose Bowl Stadium that was captured on video and has since gone viral.
