A man has been found guilty of terrorism and firearm offences after he was caught attempting to use a 3D printer to make a sub-machine gun at his home in east London.

Polish national Robert Adamski, 29, was arrested after counter terrorism officers entered his home on Lee Bridge Road and found the printer in the process of making a component, which was later identified as a part needed for a FCG-9 Mk2 firearm.

During the raid, police also recovered a number of items linked to extreme right-wing ideology. Analysis of Adamski’s phone revealed he had shared extremist documents via a Telegram group.

Commander Dominic Murphy, head of Counter Terrorism Policing London, said: “Our investigation led counter terrorism detectives to find a 3D printer actively in the process of printing out a component part for a semi-automatic firearm.

“The device still needed a number of other parts as well as technical know-how to make it viable. However, the intention to make a lethal weapon was clear.

“This proactive counter terrorism investigation has prevented two potential firearms from falling into the hands of a man who held hateful views towards ethnic minorities in London.

“I want to reassure the public we found no evidence Adamski was planning to use any weapons to target any particular communities or the wider public.

“But this case shows, attempting to create or modify 3D firearms or possessing one, even without the intent to commit harm, is illegal and will bring you to attention of the police and lead to serious criminal consequences.”

Adamski was arrested in the Walthamstow area on July 11.

Counter terrorism officers searched his address and found a number of other parts for the firearm that had already been printed, including a magazine that could hold 25 cartridges.

Detectives found a string of internet searches for 3D-printed guns and how to make them, as well as a payment for a 3D printer which was identified in his credit history in June last year.

Adamski had subsequently saved onto his computer, on July 1, a guide on how to make the FCG-9 Mk2 firearm using a 3D printer.

Adamski was charged with various terrorism and firearms-related offences on July 17.

Following a two-week trial at Woolwich Crown Court, Adamski was found guilty of two counts of possession of a component part of a firearm; possession of a document for terrorist purposes and four counts of of dissemination of terrorist publications.

He will be sentenced at the same court on November 28.
