Date Time Third man arrested after two 3D-printed submachine guns, nine stolen vehicles and explosives seized A third man has been arrested after investigators seized two 3D-printed submachine guns, nine stolen vehicles and explosives during a joint-agency operation targeting the manufacture and supply of prohibited firearms. In May last year, detectives from the NSW Police Force and Australian Federal Police (AFP) – as part of the National Anti-Gangs Squad (NAGS) – commenced an investigation after receiving information relating to the manufacture and supply of prohibited firearms across the state. During the investigation, NAGS investigators, together with the State Crime Command’s Criminal Groups Squad, seized two 3D-printed submachine guns, three firearms and 28 sticks of explosives earlier this year.
