Chicago Police are searching for a 26-year-old man who was at a concert Monday for Australian rock band King Gizzard and the Lizard Wizard, and hasn’t been seen since.

Police published a missing person’s flier for Noah Enos on Tuesday, noting that Enos is diagnosed with depression and anxiety. 

Enos is 5-feet 11 inches tall, weighs 140 pounds and has brown eyes and black hair. Chicago Police told USA TODAY no other information regarding his disappearance has been provided. 

Salt Shed told USA TODAY the venue is continuing to work with authorities to assist their location efforts and has no further statement.

Enos’ phone died around the time he went missing, according to the Independent. His girlfriend Nicole Wijs told the British outlet that Enos had been sending videos to her on snapchat of the performance until about an hour before his disappearance and she messaged him at 10pm.

“I was waiting up for Noah to come home after the concert. I waited up all night. I called hospitals,” Wijs told the Independent Thursday. “I was going crazy not hearing from him. So, I got up and drove to the venue. Obviously, I couldn’t go in because it was closed but I drove around and didn’t see anybody.”

Wijs said that her boyfriend attended the concert with his coworker. When she reached out to the coworker he told her that he briefly left Enos’ side and then couldn’t find him and later left the venue. She added that she and the venue’s security team could not find any belongings of his from that night.
