Fiona Clancy prosecutes outlaw motorcycle gang members in one of Greater Manchester Police’s first 3D-printed firearms cases

March 6, 2026

Fiona Clancy from Exchange Chambers has successfully prosecuted members of an outlaw motorcycle gang in relation to the manufacture of 3D-printed firearms, possession of firearms, supply of Class A drugs and recklessly endangering others by criminal damage. The case is understood to be one of the first prosecutions brought by Greater Manchester Police involving the manufacture of 3D-printed firearms.

Following a complex investigation, six defendants were convicted of firearms, drugs and criminal damage offences.

Members of the Bandidos motorcycle group carried out a planned revenge attack on a rival clubhouse by driving a vehicle through the wall of a building, causing extensive damage. Following the prosecution of that offence, two defendants were convicted and sentenced for criminal damage being reckless as to endangering life. The defendants’ actions were uncovered following detailed analysis of cell site and phone evidence, along with CCTV of their movements.

That offending triggered an investigation into the group, uncovering further complex offending including an offence of perverting the course of justice related to a false report of burglary and theft of the vehicle used in the criminal damage offence, as well as supply of Class A and B drugs.

House searches conducted across a number of locations in the UK uncovered extensive evidence relating to the manufacture of 3D-printed firearms, from the point of design through to the building of weapons. Two 3D-printed firearms were recovered from two separate locations, along with a further viable firearm loaded with live ammunition.

Following conviction, the six defendants were sentenced to nearly 20 years’ imprisonment.

Fiona Clancy prosecuted the case from pre-charge advice to conviction over a 4-year period, having been instructed by the CPS Complex Case Unit.
