There are claims that parts for what would be the first-ever gun produced in Britain by 3D printing, may have been seized by police in Manchester.
They were recovered during a week long operation against organised crime.
Detectives have sent the items for testing, but the owner of the shop where they were found strongly denies they were for a firearm, saying they were in fact parts from the printer itself.
