Four people were arrested in connection with a raid on multiple addresses in Växjö on Monday.
According to Smålandsposten, the operation targeted one of Växjö's criminal networks.
The four individuals are suspected of aiding and abetting attempted murder.
According to prosecutor Henrik Stiernblad, it concerns aiding and abetting the attempted murder outside Attunda district court in Sollentuna at the end of April.
It concerns an incident on 24 April where two men, already detained, were found with a weapon outside Attunda district court, he says to TT and continues:
I have now made a remand application regarding these four individuals.
Two further individuals are detained.
They are suspected of the same thing, says Henrik Stiernblad.
