Two people accused of producing and selling illegal guns and weapons are back in Harbour Grace provincial court this morning seeking bail.

Forty-nine-year-old John Byrne and 41-year-old Crystal Chislett are accused of a number of offences stemming from a major illegal weapons bust at a Harbour Grace home last week.

During the raid, RCMP seized a number of handguns and long guns, a 3D printer which produced some of the firearms, ammunition, and a body armour security uniform.

The two are charged with manufacturing firearms, possession for the purpose of trafficking, unsafe storage of firearms, having a gun loaded and accessible, and possessing guns obtained by crime.

Byrne also faces charges of flight from police and unauthorized possession of firearms.

The two spent the weekend in jail following a court appearance on Friday, and will make their case for bail this morning.

The investigation continues and police expect more charges will be laid.
