Oslo police have made four arrests following a hand grenade explosion in Pilestredet on Tuesday evening. The incident, which occurred at approximately 8:15 PM, involved one grenade that detonated and another that failed to explode but was safely handled by authorities. No injuries were reported, though police emphasized the significant damage potential of the explosion.

Two 13-year-old boys were initially taken into custody on Tuesday night, with two additional older teenagers arrested on Wednesday evening. The older suspects are both above the criminal age of responsibility and have been charged with involvement in serious illegal handling of explosives. Police confirm that the two 13-year-olds remain in the care of child protection services and will be interviewed again on Thursday.

Investigators are working under the hypothesis that the explosion is connected to conflicts between criminal actors. Police Inspector Grete Lien Metlid stated that the leading theory suggests the teenagers may have taken on a "violence as a service" assignment, carrying out the attack on behalf of others. The target appears to have been a business premises near the explosion site rather than specific individuals.

The investigation continues to examine potential connections to a separate kidnapping case involving a 24-year-old man last week. Police are exploring whether there might be a motivational link, given that the kidnapping victim reportedly has family ties to the business owner operating from the premises near the explosion site. Authorities have not commented on possible international criminal connections and emphasize that further arrests remain possible as the investigation progresses.

A Swedish court has convicted six individuals for their involvement in the murder of a 41-year-old gang leader in the Berga district of Linköping during the summer of 2024. The Linköping District Court delivered verdicts in the case, which involved eight defendants originally charged with participation in the killing. The court established that the murder was carried out according to a criminal plan orchestrated by members of an organized crime network based in the Berga area.

The victim was fatally shot in a public space near Berga Church in Linköping on August 13, 2024. Multiple gunshots struck the man in his back and head during the daylight incident, which occurred near residential buildings and a playground. Several members of the public witnessed the shooting, adding to the evidence presented during the trial.

Court proceedings revealed that a 14-year-old boy fired the fatal shots that killed the gang leader. The teenager, who has admitted to the killing, was not prosecuted due to being below the age of criminal responsibility under Swedish law. Instead, prosecutors focused on the eight older individuals allegedly involved in planning and facilitating the murder, all of whom had denied the charges against them.

Evidence presented by prosecutors included extensive documentation of movement patterns through surveillance footage, GPS data from electric scooters, and mobile phone analysis. The court determined the victim had been lured to the crime scene under the pretense of a drug transaction, with communication occurring through a special Snapchat account and a dedicated mobile phone later found buried in nearby woods. Six of the eight defendants were found guilty, with two receiving life sentences for murder while others were convicted of aiding the killing.
