Alfie Coleman was found guilty Thursday of preparing for terrorist acts after planning a mass gun attack in London [1].

The conviction highlights the ongoing threat of lone-actor terrorism and the role of digital radicalization in recruiting young adults into extremist ideologies.

Coleman, 21 [1], is a neo-Nazi from Essex and a former Tesco employee [1]. He was convicted at the Old Bailey courthouse after an undercover operation by MI5 [1]. Evidence presented during the trial showed that Coleman believed he was fighting a race war [1]. He sought to carry out a mass shooting targeting perceived enemies, including a mosque, a mayor, and his own coworkers [1].

To facilitate the attack, Coleman sought to acquire weaponry. He paid £3,500 for a pistol [2] and purchased around 200 rounds of ammunition [2]. These actions led to his arrest in 2023 [2].

Detectives said Coleman was a "dangerous individual" [3]. They also said his case reflects a "growing trend of children becoming radicalised online" [3].

Throughout the proceedings, the court detailed how the defendant's ideology drove his desire to commit mass violence. The MI5 sting operation intervened before the weapons could be used in a coordinated attack [1].

"dangerous individual"

This case underscores the shift in domestic security priorities toward combating online radicalization. By targeting a diverse set of victims—including public officials and private employees—the plot demonstrates how neo-Nazi ideologies can broaden their scope of violence beyond traditional political targets to include any perceived enemy of the cause.
