Overview
- Police shut the Theresienwiese after finding a farewell letter tied to a Lerchenau house fire that referenced a 'bombiges Erlebnis' at the Oktoberfest.
- At 11:04 a.m., the city’s Integrated Control Center sent a Cell Broadcast across Munich that sounded a siren and displayed the label 'Extreme Gefahr' on many phones.
- The federal civil protection agency (BBK) said the wording attaches automatically to the medium of three warning levels and noted that customization is constrained but under review.
- Warnings appeared inconsistently across Cell Broadcast, Katwarn and NINA, with some devices showing citywide risk, others lacking location detail, and some receiving nothing, prompting confusion in offices and schools.
- The festival reopened at 5:30 p.m. after searches and visitors returned Thursday, while Bavaria’s interior minister and the Wiesn chief criticized the alert’s clarity and called for improvements.
