"There is little evidence to suggest that those who have put the scaffolding up, not at all trained for it. It is fatal to work on the scaffolding. People are angry, even if it is declared, nothing happens," says Thomas Strømholt to A4 Now and stresses that he is not speaking on behalf of the protesters stilladsarbejdere.

He does not know whether it was their members of the 3F, which was the scaffold.
