A teenage student from South West London who attended secondary school in Kingston has been convicted and sentenced for crimes of far-right terrorism and child abuse imagery.

Harry Vaughan of South-West London was sentenced yesterday (Monday, November 2), to two years in prison, suspended for two years, a ten-year terrorist offender notification order, and ordered to attend a number of programmes including for deradicalisation, after her admitted "14 terrorism offences" related to extreme right-wing ideology and "two child abuse image offences", the Met Police have said.

Detectives from the Met Police Counter Terrorism (CT) Command arrested Vaughan on June 19 last year after he was identified as one of a number of people posting messages on a far-right extremist website.

Specialist officers from the Met's CT Command recovered a computer, mobile phones and Kindle from Vaughan’s family home.

Forensic specialists were able to trace the activity on Vaughan’s computer from the first day he switched it on.

The Met said their digital forensic specialists retrieved "4,200 images and 302 files, including an extreme-right wing terrorist book and documents relating to Satanism, Neo-Nazism and anti-Semitism" from Vaughan’s devices.

Vaughan’s terrorism convictions relate to specific documents, but prosecutors highlighted that the thousands of other files were evidence of the extreme mind-set underlying his offending.

The incriminating files included:

- graphics encouraging acts of terrorism in the name of the proscribed organisation Sonnenkrieg Division;

- a guide to killing people;

- bomb-making manuals.

Detectives also identified that Vaughan had downloaded and watched two child abuse videos, classified category A - the most serious type," a Met spokesperson said.

Met Police Commander Richard Smith said:

"Harry Vaughan is an intelligent young man who was predicted A-star grades and aspired to study computing at university.

"Yet online, he was an enthusiastic participant of right-wing terrorist forums. He made and published vitriolic graphics encouraging terrorism and signposted people to violent terrorist guidebooks online.

"His case illustrates it is possible for any young person to be susceptible to radicalisation, so today I really want to appeal to everyone to be as vigilant as possible for signs that a young, loved one may be in trouble.

"If you have any concerns at all, act decisively – talk to the police before it’s too late. We have officers who are specially trained and ready to help people who are becoming radicalised to choose a better life for themselves."
