Jefferson County officials are asking the public for help in identifying a suspect who allegedly assaulted a man and left him with several broken bones at an October Red Rocks concert.

The assault took place during the Martin Garrix concert on Oct. 22, when the suspect and victim got into an argument over general admission seating in Row 24, the Jefferson County Sheriff’s Office said on social media Tuesday.

During the argument, the victim suffered multiple broken facial bones and a broken leg, the office said.

The suspect, described as a 5-foot-9-inch man who was wearing a striped button-up shirt, could be seen walking in a group with six other people in surveillance footage after the concert, according to the post.

Anyone who witnessed the assault is asked to contact the Jefferson County Sheriff’s Office tip line at (303) 271-5612 or via email at [email protected] with case reference number 25-18282.
