Customs officers at the Hauptzollamt Singen found a SIG assault rifle in the trunk of a car during a vehicle check in Switzerland, the service said. The incident happened on 7 November 2025 during an inspection of a vehicle registered in the Canton of Glarus. The driver and passenger said they were travelling to Konstanz to eat. During the search, customs discovered the weapon unsecured in the car’s trunk. The driver, a man in his early 30s and a Swiss reservist, said he had forgotten to remove the rifle after a training session. A criminal procedure was opened for an alleged violation of the Kriegswaffenkontrollgesetz, the war weapons control law. The rifle was seized. The Zollfahndungsamt Stuttgart took over the further investigation.
