A 20-year-old Birmingham man named Adam Mahmood has been sentenced to 4 years in a young offender institution for possessing a video that provided detailed instructions on how to make explosives similar to those used in past UK terror attacks. Police also found an alarming collection of medieval weapons in Mahmood's bedroom, though there was no evidence of an imminent terrorist act. The judge stated that Mahmood had 'terrorist motivations' and the presence of the video and weapons was a 'clear warning sign'.

Why it matters

This case highlights the ongoing threat of homegrown extremism and the challenges authorities face in identifying and stopping potential lone-wolf attackers before they can act. The possession of bomb-making instructions and an arsenal of weapons, even without an immediate plot, demonstrates the need for continued vigilance and effective counter-terrorism efforts.

The details

Adam Mahmood was found guilty after a trial in September 2026 of possessing a video that provided detailed instructions on how to make explosives with a detonator and shrapnel. Mahmood claimed he had watched the video on fast-forward and skipped parts, but the judge noted the visuals and subtitles clearly showed its nature as a bomb-making guide. In addition to the video, police discovered medieval weapons including swords, knives, an axe, and a catapult in Mahmood's bedroom, which he linked to an interest in Islamic history.

  • Mahmood was sentenced in September 2026.
  • The video was sent to Mahmood by a TikTok user prior to his arrest.
