A hand grenade from World War II was discovered in Haugenstua, Oslo, prompting police to conduct a controlled explosion on Friday afternoon. Major Gabriel Langfeldt reported that the detonation took place at 5:25 PM, with responders now focusing on a manual search for any additional hazards or evidence in the area. Tomm Berger, the operational leader, stated that after ensuring safety, they would vacate the site.

The grenade was located following the relocation of a container in an area where container rental services operate. The bomb disposal squad was dispatched to evaluate the situation, ultimately determining that the grenade was unstable and necessitated in-situ detonation to prevent any potential danger. The discovery raises questions about how long the grenade had remained undetected in the area.

While the specific length of time since the grenade was placed there is uncertain, it is confirmed to be a relic from World War II. Authorities believe it may not have been there since the period of the war itself, indicating that these historical artifacts can linger unnoticed in urban settings. The incident serves as a reminder of the lingering dangers posed by unexploded World War II ordnance in various parts of Europe.
