Canadian Machine Gun Seized

U.S. customs agents inspecting cargo at Detroit’s Fort St. cargo facility found a fully assembled .50-caliber machine gun inside a box from Canada labelled gun parts.

The gun was seized and the U.S. importer faces an unspecified fine.

According to officials, the shipment failed to satisfy federal importation procedures for firearms.

The weapon is being shipped back to the Canadian company attempting to ship it.
