The Dutch Safety Board has started an investigation into the collapsed roof of the AZ-stadium. During the past weeks the Board has completed an exploratory investigation, which resulted in an interim warning for the remaining roof.

The Board will investigate the direct and underlying causes of the incident, with the aim of learning lessons for the future. The design, authorisation, construction, and maintenance of the stadium will be included in the investigation.
