In September 2025, a grenade exploded in Pilestredet, Oslo, leading to police detonation of another grenade in the area. Fortunately, there were no injuries reported as a result of the explosion. Two 13-year-old boys were brought in for questioning; one was at the explosion site while the other was arrested at a child welfare facility. Recently, it was reported that the case against one of the boys was dropped, as he is below the age of criminal responsibility in Norway.

Øystein Storrvik, the lawyer representing the boy whose case was dismissed, stated that his client had consistently exercised his right to remain silent and had not provided any explanations during the investigation. As a result, the case was closed, and it was noted that the matter has been handed over to child welfare services for further handling. The second boy's legal status remains unclear, as his attorney, Marius Dietrichson, indicated he has not been updated about any changes in his situation.

The incident has raised serious concerns regarding youth involvement in violent acts, as the grenade case is being linked to broader issues involving a group named Foxtrot. This connection may highlight potential gang activities or trends among young individuals in Oslo, prompting discussions on how to better address prevention and rehabilitation efforts for youth involved in criminal activities. The decision to transfer cases to child welfare emphasizes the challenges faced in balancing accountability and protection for minors in the legal system.
