Indepedent body the Dutch Safety Board has started an investigation into the stadium roof collapse at FC Twente’s ground, the Grolsch Veste.
The accident occurred at about 12pm local time on the 7 July which killed two and injured a further 16.
Investigators will be focusing on finding out the direct cause of the stadium roof collapse and the circumstances surrounding it.
Construction on the cantilever roof was close to completion when it collapsed at one end of the stadium. The extension is part of a £44.1M project to expand the stadium from 13,500 capacity in 2006 to 32,000 for the start of the new season in August.
A preliminary report is due out in August with the full investigation lasting up to nine months.
