A Los Angeles man was arrested at this past weekend’s Outside Lands Music and Arts Festival as police claim he stole nearly $4,000 worth of wristbands from the event’s box office.

The San Francisco Examiner reports that according to police and witnesses, 29-year-old Shawheen Younai was selling wristbands on Friday. The paper reports that they “had been reserved for vendors, guests of artists and patrons with backstage access.”

San Francisco police said the wristbands were in an envelope that went missing from the box office. Younai was booked on charges of second-degree burglary and possession of stolen property.

Police said for the most part, the festivities were fairly uneventful in terms of arrests, although the official arrest numbers have not been released.
