Greater Manchester Police assistant chief constable Steve Heywood urged caution over the 3D-printed parts found:
We need to be absolutely clear that at that this stage, we cannot categorically say we have recovered the component parts for a 3D gun.
What we have seized are items that need further forensic testing by national ballistics experts to establish whether they can be used in the construction of a genuine, viable firearm.
We will also be conducting a thorough analysis of computers we have recovered to establish any evidence of a blueprint on how to construct such a weapon.
