Alfie Coleman Convicted of Preparing Terrorist Attack in England

5/1/2026, 7:10:24 PM

Core Event: Trial, Conviction and Arrest

A jury at London’s Old Bailey found 21-year-old Alfie Coleman guilty of preparing terrorist acts after he arranged to purchase a Makarov pistol, five magazines and roughly 200 rounds of ammunition from undercover MI5 officers on 29 September 2023. Video from the operation shows Coleman handing over £3,500 in a Land Rover Discovery and receiving a holdall containing the weapon in a Morrisons car park in Stratford, east London. He was subsequently detained, his home searched, and he was remanded pending sentencing on 8 July 2024.

Background & Context: Online Radicalisation

Coleman, from Great Notley, Essex, began consuming extreme-right material at age 14. By July 2021 he emailed the white-supremacist group Patriotic Alternative expressing a desire to join activism. During the 2020 Covid-19 lockdowns his consumption intensified; he idolised Adolf Hitler and Thomas Mair, the murderer of MP Jo Cox. His devices later contained manifestos by Dylann Roof and Brenton Tarrant, and a personal diary-style manifesto urging the death of anyone “not on our side.”

Timeline of Key Developments

  • 2015 (?age 14): Starts browsing neo-Nazi content online.
  • July 2021: Contacts Patriotic Alternative.
  • September 2022: Compiles a “hate list” of coworkers and customers.
  • Early September 2023: Attempts to acquire a Skorpion automatic weapon and an AK-47 in France; abandons plan.
  • 29 Sept 2023: Meets undercover officer, pays £3,500, receives pistol and ammunition; arrested minutes later.
  • April 30 2024: Jury convicts Coleman after retrial.

Data & Statistics

  • Financial outlay: £3,500 for the pistol and ammunition; £2,500 saved in a personal account.
  • Firearms: Makarov pistol, five magazines, 200 rounds; earlier interest in Skorpion and AK-47.
  • Evidence seized: 10 documents with weapon-making instructions, knives, a stone axe, an air rifle, a crossbow flyer, a Black Sun flag, a swastika-etched rock, and extremist literature.
  • Charges: Guilty pleas to possession of a firearm and ten “documents likely to be useful to terrorists.”

Why It Matters: Threat of Home-Grown Extremism

The case illustrates a growing pattern of youth radicalised online, capable of moving from digital propaganda to concrete procurement of weapons. Police highlighted the risk of “mass attack” intentions, noting Coleman’s plans included a mosque, the Lord Mayor of London, and even a cash-machine bomb. The successful sting underscores the importance of coordinated counter-terrorism operations between MI5 and Metropolitan Police.

Official Statements & Responses

Detective Chief Superintendent Helen Flanagan of the Met’s Counter-Terrorism Command said the verdict confirms the effectiveness of MI5-Met collaboration and described Coleman as “a really dangerous individual” whose intent extended beyond a single target. Bethan David, head of counter-terrorism at the Crown Prosecution Service, called him “a dangerous man who planned to commit a terrorist attack to further his extreme racist and white supremacist agenda.” Prosecutor Nicholas de la Poer KC noted Coleman’s “seething with hatred” while compiling his hate list.
