Police in Neuerberg, Germany, interrupted the Rock am Ring music festival and evacuated as many as 90,000 attendees on Friday, June 2, due to what was called a significant security threat, according to festival organizers and police.

Concertgoers were said to be disappointed, but departed the venue in a calm and orderly fashion, according to eyewitnesses, though some said they felt more safe there than at a nearby camping area for attendees.

The performance of at least one major act, Rammstein, was canceled due to the threat.
