It is a confirmed detonation, smaller form. It is a few window panes that have been broken. There are no personal injuries, says Andreas Aaw, duty officer with the police, to the magazine.
The alarm about the loud bang came at 01.41 on the night of Midsummer. The police are investigating the incident as gross general public destruction.
