Three people arrested as part of an investigation into right-wing terrorism have been charged with possessing components of a 3D printed firearm.
The two men and a woman appeared at Westminster Magistrates' Court on today (Friday, 14 May) charged with terror offences along with another man, police said.
All four were arrested on May 1 at addresses in West Yorkshire, North Wales and Wiltshire.
Counter Terrorism Policing North East said three of the four people charged face an allegation that "they possessed an article, namely components of a 3D printed firearm, in circumstances which give rise to a reasonable suspicion that their possession was for a purpose connected with the commission, preparation or instigation of acts of terrorism".
Daniel Wright, 29, of Whinfield Avenue, Keighley, West Yorkshire, is charged with offences of disseminating a publication that encourages terrorism, possessing articles connected with an act of terrorism, and possessing a document or record likely to be useful to a person committing an act of terrorism.
He is also accused of possessing a firearm and manufacturing a firearm.
Liam Hall, 30, of Hill Top Walk, Keighley, West Yorkshire, is charged with possessing articles connected with an act of terrorism as well as possessing and manufacturing a firearm.
Stacey Salmon, 28, of Hill Top Walk, Keighley, West Yorkshire, is charged with possessing articles connected with an act of terrorism and possessing a firearm.
Samuel Whibley, 28, of Derwen Deg, Menai Bridge, Anglesey, is charged with the encouragement of terrorism and disseminating a terrorist publication that encourages terrorism.
Wright, Hall, Salmon and Whibley appeared at Westminster Magistrates' Court via video-link on Friday morning and were remanded in custody to appear at the Old Bailey on May 28, Counter Terrorism Policing North East said.
A 16-year-old male from Swindon, who was arrested as part of the same operation, was released from custody without charge a week ago, a spokesman confirmed.
