British Army Chef Jailed for Nearly Four Years After Police Discover Homemade Medieval Cannon, Explosives and Weapons

A British Army soldier who amassed a disturbing collection of weapons, made explosives and built a crude homemade cannon has been jailed after a counter-terrorism investigation uncovered his links to extreme right-wing ideology. Mark Broadhurst, 28, was sentenced to 46 months in prison after a court found that his weapons and online activities were connected to an extremist agenda that posed a serious potential danger to the public.

Broadhurst, an Army chef, came to the attention of counter-terrorism officers while they were investigating other individuals associated with far-right groups. Detectives discovered his activity on online forums, where he reportedly shared hateful, racist and aggressive messages and expressed extreme views targeting Black, Asian, Muslim and Jewish people. His online discussions also included references to anarchy, the collapse of society and the possibility of forming an armed militia.

The investigation took a more alarming turn in September 2024, when Broadhurst was arrested at Catterick Garrison in North Yorkshire, where he was serving. Police subsequently searched his military accommodation and his home in Chesterfield, Derbyshire. What officers discovered was a substantial collection of weapons and potentially dangerous materials, including gunpowder, ammunition, air pistols, rifles, crossbows and bolts, six large knives and a baseball bat.

Among the most unusual discoveries was a homemade cannon constructed from a piece of wood and a pipe secured with duct tape. An expert described the crude device as resembling a firearm from the 14th century. Although primitive compared with modern weapons, its presence alongside gunpowder and other weaponry intensified investigators’ concerns about Broadhurst’s activities and intentions.

The court also heard that Broadhurst had been actively obtaining components needed to make explosives. Prosecutors presented evidence of his online communications and his interest in violent extremist ideas. Some of his messages reportedly suggested that he wanted to be remembered in history books and criminal records for terrorism and killing police officers. Investigators also established that he maintained contact with three individuals who were later convicted of terrorism-related offences and were associated with supremacist ideology.

Broadhurst admitted possessing explosives and committing a firearms offence, but he disputed the claim that his actions were motivated by terrorism. His defense argued that the weapon he had constructed had not been used to threaten anyone. His lawyer also presented a positive reference from a superior officer, who described him as an excellent mentor to junior members of the catering team and praised his professional standards in the Army.

However, the judge rejected the argument that the offences should be treated as unrelated to terrorism. Mr Justice Hilliard concluded that Broadhurst had made the firearm and gunpowder partly to ensure that members of extremist groups would take his statements and threats of serious violence seriously. The court determined that his actions were intended to strengthen his standing among individuals who shared his extreme right-wing beliefs.

On October 14, 2026, Sheffield Crown Court sentenced Broadhurst to three years and ten months in prison, equivalent to 46 months. He will also be subject to a 10-year notification order. Counter-terrorism officials welcomed the sentence, emphasizing that the investigation had exposed both his extremist mindset and his efforts to acquire weapons and materials capable of causing serious harm.

Detective Chief Superintendent James Dunkerley, head of Counter Terrorism Policing North East, said the investigation revealed extensive online conversations with people holding similar extreme views. He highlighted Broadhurst’s efforts to obtain explosive-making components and his accumulation of multiple weapons. Officials stressed that the sentence reflected the seriousness of his conduct and the potential danger he posed.

The case has also prompted a strong response from the British Army, which stated that racist and extremist ideologies have no place within its ranks. Although most of the offending took place before Broadhurst joined the military, the discovery of weapons at both his home and his barracks accommodation underscored the importance of identifying potential threats before they escalate. For investigators, the case demonstrates how online extremist activity can lead to real-world concerns when accompanied by weapons, explosives and threats of violence.
