The Oslo explosion in Pilestredet near Bislett occurred on 23 September 2025 at 20:29 CEST, when a hand grenade detonated in the street; a second device was safely detonated later by the bomb squad.
No casualties were reported. Police detained two 13-year-old boys and are probing whether the attack is linked to a criminal conflict and ordered as “violence as a service.”

investigation focus: ‘violence as a service’ and criminal conflict
Police state their main hypothesis is a targeted attack connected to a dispute between criminal actors. Given the age of those involved, investigators are examining whether the boys acted on instructions from older criminals—a pattern described as “violence as a service.” The case is being investigated as gross unlawful handling of explosives and related offences.
Link explored to recent kidnapping case and cross-border gangs
Investigators are assessing potential ties to a kidnapping (deprivation of liberty) case reported in Oslo the previous week, in which a 24-year-old was reportedly abducted and taken out of Norway. Norwegian outlets have also reported possible connections to Swedish criminal networks such as Foxtrot, known for recruiting minors and operating across borders. Authorities emphasize that these lines of inquiry are preliminary.
Official responses and public reassurance
Oslo Police underline the incident’s seriousness and say visible patrols will remain in the area to reassure residents. Prime Minister Jonas Gahr Støre called the attack “totally unacceptable,” noting concerns about the involvement of very young people and highlighting the need for international cooperation against cross-border gangs. The Justice Minister likewise condemned the attack as unacceptable and serious.
What we know and what remains unclear
Police confirm that two grenades were involved in the incident: one exploded on Pilestredet, while the second was neutralised in a controlled detonation by the bomb squad. No injuries were recorded, but the blast caused material damage to nearby buildings and street infrastructure. Two 13‑year‑old boys have been detained and are currently under the child‑protection system.
Several key points remain under investigation. Detectives are working to establish who commissioned the attack and the exact motive, determine the full number of individuals involved beyond the minors, and clarify the extent of any link to the reported kidnapping case and to cross‑border networks.
Sweden gang example: Oslo is like Malmö?
The incident fits a wider pattern in parts of the Nordic region and EU where criminal networks use youths for high‑risk tasks, including grenade attacks and arson. Norwegian authorities have repeatedly warned against this trend and point to developments in Sweden—notably in Malmö—where gang wars have involved recurrent explosions and shootings, often with minors recruited by senior criminals. In response, police stress stronger cross‑border cooperation, shared intelligence on explosives and weapons flows, and early‑prevention measures in schools and communities to keep children away from organised crime.
Police are expected to interview the minors and pursue forensic and intelligence-led inquiries to establish commissioning chains, supply of explosives, and cross-border links. Further updates will follow as authorities clarify the motive, perpetrators, and consequences for local security in Oslo and the wider Nordic region.
