(1)Any constable may demand from any person whom he believes to be in possession of, or to be using or carrying, a firearm or ammunition (except in circumstances where possessing, using, or carrying a firearm or ammunition without a firearm certificate does not constitute an offence) the production of his firearm certificate.
(2)If any person upon whom a demand is so made fails to produce the certificate, or to permit the constable to read the certificate, or to show that he is a person who is exempted under section one, subsection (8), of this Act from the necessity of having a certificate, the constable may seize and detain the firearm or ammunition, and may require that person to declare to him immediately his name and address.
(3)If any person refuses so to declare his name and address, or fails to give his true name and address, he shall be liable on summary conviction to a fine not exceeding twenty pounds, and the constable may apprehend without warrant any person who refuses so to declare his name or address, or whom he suspects of giving a false name or address, or of intending to abscond.
