- Authorities say several people were wounded but have not released a final casualty count; multiple outlets and police reports indicate at least two girls were seriously injured and taken to hospital.
- Early reporting contains conflicting details about the weapons used, with police saying many victims appear to have stab wounds while also noting investigators cannot rule out a shooting.
- More than 15 patrol cars, specialised units and a police helicopter responded to secure the Welfen-Gymnasium and its vicinity, and a support centre for relatives was set up at the Bahnhofstrasse fire station.
- The case is under active investigation with police keeping an open mind on motive, prosecutors and child-protection rules likely to shape public disclosures because the suspect is a juvenile.
