A significant police operation was launched in Ullensaker, Norway, in late May following a concerning emergency call. Authorities now believe the call, reporting a serious threat, was a hoax. The incident prompted a large-scale deployment of police resources to the area. Details regarding the nature of the reported threat have not been fully disclosed, but it was initially treated as credible. Investigations led police to conclude the call was unfounded, diverting resources from other potential incidents. No arrests have been made, and the investigation into the origin of the false report is ongoing. Police are urging caution regarding misuse of emergency lines.
