A 28 year-old RAF airman from Norfolk who attempted to manufacture sub machine guns has started a six year jail sentence.
John Yelland, who until his arrest had been a serving airman at RAF Marham, admitted eight offences which also included possession of guns and ammunition.
His wife Maimie Yelland was jailed for six months after she admitted transferring criminal property.
The court heard that Yelland had been using mail services to post parts of the weapons to himself and had been manufacturing them in his own home.
Chief Superintendent Nick Davison, from Norfolk Police has welcomed the sentences saying

"Yelland thought nothing of making and storing the weapons and it is pleasing to see this man behind bars with a lengthy custodial sentence and restricted in his use of electronic communication devices once he is released.”
