Two teenagers charged over suspected right-wing terrorism

Ms Vinogradova was first arrested on 4 August at a Cheshunt address on suspicion of being in possession of a firearm and collection of information likely to be of use to a terrorist, police said.

The property was searched and she was taken to a police station before being released on bail, pending further enquiries.

On 10 August, she was arrested again, along with Mr Clark, at an address in Cheshunt.

Further searches were then carried out of the Cheshunt address and an address in Ilford.

Following liaison with Crown Prosecution Service, charges were brought on Thursday.

The head of the force’s Counter Terrorism Command, Commander Dominic Murphy, said: “These are extremely serious charges but I would urge the public not to speculate any further about this case at this time and allow the criminal justice process to run its course unimpeded.

“While we are not able to comment in any detail about the investigation now that these charges have been brought, I want to reassure the public that at this time we do not believe that there is any wider threat related to this investigation, although our investigation very much continues.

“I also want to make clear that our investigation into this matter is not as a consequence of the disorder across the country which occurred following the terrible events in Southport.”
