Police have recovered a home-made shotgun, drugs and cash in New Lambton.
It's alleged the shotgun, revolver, cartridges and gun parts were found following a routine traffic stop on Newcastle Road at around 8pm last last night.
A man and woman - both aged 23 - were arrested as a result.
Detectives executed a search warrant at a New Lambton home later that night, before officers allegedly recovered more ammunition, meth, cannabis, suspected steroids, other medication and cash.
The man arrested has since been charged and refused bail - while the woman has been released pending further inquiries.
