Norwegian police have arrested eight individuals in the Troms region of northern Norway and seized drugs, cash, and firearms from a criminal network.

The police are calling for a press conference due to an increased threat from Swedish criminal networks in Norway, with a significant concern in Troms.

Investigations reveal that the relationship with Swedish networks dates back several years.

This isn't the first warning from Norwegian authorities about Swedish gang activities crossing the border, showing a trend of weekly crimes.

The press conference will provide further details on the recent investigation and the ongoing threat.
