A boy was arrested in Kungsbacka during the night against Friday. In connection with this, an object that the police suspect is dangerous was found.
They have handled this object and made the assessment that it was live, says duty officer Johan Josarp to Göteborgs-Posten.
The boy, "a younger person", is known to the police from before, says Josarp to the newspaper. A preliminary investigation into attempted public endangerment has been initiated.
On Friday morning, the cordons were lifted.
