Ripoll, Girona – The Guardia Civil in Spain has arrested a man in connection with the possession of illegal weapons, and for posting instructions on the internet about how to make them at home.
The police said that they discovered a workshop for illegally manufacturing weapons using 3D printers, as well as projectiles for gas weapons, inside a detached house located in Ripoll, Girona.
According to official reports, the suspects also posted content on internet forums and platforms, explaining different ways to make weapons capable of firing potentially lethal shots. The man also spread explicit and detailed information on how to make highly lethal homemade explosives, as well as designs for banned parts such as silencers, barrels, and triggers.
Police said that a 3D printer was also found which they suggest was used by the man to manufacture illegal parts used to assemble gas weapons of different calibres.
Necessary raw materials used for the manufacture of the weapons were also found. This included manuals on how to use, handle and manufacture firearms using 3D printing.
