Alfie Coleman, a 21-year-old extremist, has been convicted of preparing a terrorist attack after meticulously planning a mass shooting targeting customers and colleagues at a Tesco supermarket where he worked. Caught in a high-stakes MI5 operation, Coleman attempted to purchase a Makarov semi-automatic pistol, multiple magazines, and hundreds of rounds of ammunition with £3,500 saved from his part-time job.
Disturbing “Kill List” and Racial Hatred Exposed
The Old Bailey revealed Coleman compiled a chilling “kill list” containing names of former co-workers and shoppers he labeled “race traitors” due to their interracial relationships. The list included detailed personal information such as vehicle registration plates and physical descriptions. One entry identified a checkout worker whose mixed-race husband provoked Coleman’s racial animosity, noting her car’s make and color and describing her as having “short blonde hair with bits of pink.”
Idolization of Far-Right Terrorists
Prosecutors exposed Coleman’s deep allegiance to extremist right-wing ideology. He idolized Adolf Hitler and notorious terrorists like Thomas Mair, who brutally murdered MP Jo Cox in 2016. Counterterrorism officials emphasized Coleman’s intent to acquire automatic weapons to execute a mass shooting, with mosques among his potential targets.
MI5 Sting Operation Unveils Plot
For months, Coleman communicated with undercover MI5 agents via encrypted messaging platforms, unaware of their true identities. On 29 September 2023, officers surrounded him in a Morrisons car park in Stratford, Essex, where he was caught attempting to finalize the illegal firearm purchase. Security footage captures Coleman dropping to his knees and submitting as armed officers handcuffed him, moments after placing cash on the passenger seat and retrieving a holdall containing a deactivated pistol from his vehicle.
Legal Proceedings and Guilty Verdict
Coleman had earlier pleaded guilty to possession of prohibited firearms and ammunition, alongside 10 counts linked to possessing materials useful for terrorism. These items included extremist literature such as the White Resistance Manual, The Terrorist Explosives Handbook, and 21 Techniques Of Silent Killing. Despite this, he denied orchestrating a terror attack, with a jury initially deadlocked on that charge after he expressed regret over his past beliefs.
His defense portrayed him as a lonely, isolated teenager affected by COVID-19 lockdowns, asserting that although obsessed with firearms, he lacked intent to kill. However, a retrial concluded with Coleman’s conviction for preparing acts of terrorism.
Growing Threat of Youth Radicalization
Detective Chief Superintendent Helen Flanagan of the Metropolitan Police highlighted how Coleman’s case exemplifies the alarming trend of young individuals drawn into violent extremism. Statistics show one in five counterterrorism arrests involve suspects aged 17 or under, with half of the government’s Prevent scheme referrals concerning children.
Early Signs of Extremism and Dangerous Plans
Police traced Coleman’s radicalization back to age 14, when he first searched for the Ku Klux Klan online. Analysis of his devices uncovered extensive far-right content, including manuals on weaponry and explosives. A pivotal piece of evidence was his detailed diaries outlining terrorist plans and a personal manifesto that mirrored writings by notorious mass murderers like Dylann Roof, Anders Breivik, and Brenton Tarrant, whom Coleman called “warriors.”
His writings named London Mayor Sadiq Khan as a target—though he mistakenly recorded the address of the ceremonial Lord Mayor. Other plots included bombing an ATM and attempting to hijack a plane, the latter dismissed by prosecutors as immature but indicative of his dangerous mindset.
Undercover Operation and Final Arrest
In mid-2023, Coleman’s growing activity in extremist chat groups and repeated inquiries about acquiring firearms drew MI5’s attention. Undercover agents gained his confidence and negotiated selling him a Skorpion submachine gun and AK47, alongside ammunition. Coleman planned to retrieve these weapons in northern France, even researching mosque locations ominously within that region.
He arranged travel to France on 6 September but cancelled, prompting undercover officers to propose selling him a Makarov pistol for £3,500. Police described Coleman as being in the “advanced stages of radicalization” and actively planning an attack, necessitating immediate intervention.
Evidence Seized and Ongoing Threat
Authorities recovered a collection of knives, a petrol bomb, and an SS flag from Coleman’s home, underscoring his violent intentions. Prison notes revealed neo-Nazi symbols, swastikas, and quotes from cult leader Charles Manson, with Coleman vowing, “Under no circumstances will I betray my race for less jail time.”
DCS Flanagan stressed that neither police nor the Prevent program had prior contact with Coleman, and his parents were unaware of his extremist interests or dangerous mindset. “They had no idea about the toxic and violent ideology he had embraced,” she said.
This conviction sends a stark warning about the urgent need to detect and intervene in youth radicalization before it escalates into deadly violence.
