A convicted right-wing extremist from Maidenhead will spend more time in jail after he threatened to shoot prison and probation staff.  

Nicholas Brock, formerly of Lancaster Road in Pinkneys Green, was found guilty of two counts of making threats to kill by a jury verdict at Oxford Crown Court today (September 16).

The 57-year-old had been jailed in 2021 on three charges of possessing a document likely to aid a person committing or preparing an act of terrorism.

He has now been handed an extra four years' imprisonment with a further year to be spent on licence.

Head of Counter Terrorism Policing South East detective chief superintendent Claire Finlay said Brock had an ‘extreme right-wing mindset’ and ‘continued to pose a risk of significant harm’.

While behind bars, Brock made threats to prison staff and claimed he knew people who could reactivate firearms which he would then use against prison and probation staff on his release.

Counter terrorism police raided his home on March 6 this year, where they found ‘numerous deactivated firearms’.  Officers also discovered a knuckle duster, knives, and swords, including one disguised as a walking stick.

Brock was charged four days after the raid, over threatening to shoot a male prison guard on May 20 last year, and a female probation staff member five months later on October 9.

The extremist was already serving a four-year sentence at HMP Bullingdon in Bicester, having been found guilty of terrorism charges after a police investigation in 2020.

He was also found to have collected Nazi memorabilia from WWII, own racist videos, and have footage from the Christchurch massacre where 51 people were shot in an attack on a mosque.

Police found guns and swords at Brock's home.


DCI Finlay said: “Brock’s behaviour has demonstrated that his extreme right-wing mindset did not diminish during his time spent in prison and his aggressive behaviour was escalating as his prison release date approached.  

“Following the investigation by specialist counter terrorism policing officers from my unit, it was clear that Brock continued to pose a risk of significant harm towards the victims in this case, as well as towards members of the public from minority backgrounds, and those in positions of authority.  

“Brock claimed to know criminal associates who could reactivate his firearms and so it was vital that we took swift action to keep our communities safe from the harm he poses.”
