Far-right extremist, 19, who plotted Satanic terror attack admits encouraging woman to livestream taking her own life and 'filmed himself trying to strangle a cat'

A teenage member of a satanic far-right extremist group has pleaded guilty to encouraging the suicide of a young woman so others could watch online.

Cameron Finnigan, 19, who lived with his adoptive parents and sister in a four-bedroom detached house in Horsham, West Sussex, pleaded guilty to encouraging or assisting suicide on or before March 4 this year.

The act was to be livestreamed to a group of Finnigan's online associates but never took place.

He also accepted that he had a terrorism document called the NLM x MKU Kill Guide - a far right manual produced by an American group called No Lives Matter and a Russian group called Maniac Murder Cult which borrows ISIS tactics.

Finnigan pleaded guilty to criminal damage after spraying graffiti across 13 walls and fences in the town with his nickname 'Acid', a satanic pentagon, and the name of the organisation he had joined, '764.'

He pleaded guilty causing £1,000 worth of criminal damage to a car by cracking the windscreen, puncturing a tyre and scratching the bonnet.

In a fifth charge, he also pleaded guilty to possessing seven category A indecent photographs of a child and a category A video.

Finnigan denied causing unnecessary suffering to an animal after he made a video in which he apparently tried to strangle a cat. The charge was ordered to lie on file.

A previous hearing was told that Finnigan had discussed attacking a single homeless person who was living in a tent in one online discussion.

Following his arrest, Finnigan admitted that he became involved with a Satanic extremist group named '764', in October or November last year.

The group is associated with a notorious far-right Satanic group called the Order of the Nine Angles.

Both groups are said to have a 'militant accelerationist ideology' which seeks to provoke a race war.

When police arrested him at 6.40pm on the evening of March 26 they tried to use a 'contain and callout' tactic that required him to come out of the house because they believed he had access to firearms.

His parents and sister left the house, but Finnigan was in his bedroom wearing a headset and did not respond.

He was arrested in his bedroom on suspicion of threats to kill and the possession of a firearm. He made no response but nodded that he understood and was described as having 'sighed heavily'.

At the time he was apparently in a live online discussion and officers reported people sending warning messages in the various groups he was logged into and users starting to delete content.

During an 'urgent safety interview' Finnigan provided the pin to one of his devices, 1969 and confirmed that he used Instagram and the gaming messaging app Discord, but said he did not know the login details.

The PIN was said to be a reference to the year the 'Satanic Bible' was first published.

John Lyons, defending, told the court that Finnigan had a 'complicated mental health history' and asked for a psychiatric report before sentence.

Bill Emlyn Jones KC, prosecuting asked for the issue of dangerousness be addressed in a pre-sentence report.

The judge Mrs Justice Cheema-Grubb ordered the report and asked for a statement or letter to be sent to the court from Finnigan's parents.

He appeared by video link from Tameside prison in London and spoke only to enter his pleas.
