Lengthy prison sentences for possessing a firearm will help police tackle the potential new "phenomenon" of 3D guns, Greater Manchester Police Chief Constable Sir Peter Fahy told Sky News.
He said: "We will need to look at this new development but I do think it is crucial that in this country illegal possession of a firearm does attract a very lengthy prison sentence
"As long as that continues, I think that will help as a huge help to us in controlling what might be this new phenomenon about 3D guns."
