A 20-year-old man from Birmingham has been sentenced to four years in prison for a terrorism offence after he was found in possession of a detailed instructional video on how to construct an explosive device.
Arrest and Discovery of Dangerous Material
Adam Mahmood, of Platt Brook Way in Sheldon, was arrested at his home in April 2024. Officers from Counter Terrorism Policing West Midlands seized his mobile phone, leading to the discovery of extremist content.
Forensic analysis revealed a 15-minute video that provided step-by-step instructions for manufacturing a bomb, complete with a detonator and shrapnel. The court heard that Mahmood had specifically searched for this particular video, which detailed how to make a device similar to those used in past UK terror attacks.
An expert who assessed the material stated the guide was 'easy to follow even for someone with no previous training' and was therefore considered incredibly dangerous.
A Cache of Weapons and Propaganda
Further examination of Mahmood's phone uncovered additional terrorist propaganda, including videos depicting executions. Police also found messages discussing the manufacture of a sword, and a part-made sword was discovered during a search of his bedroom.
The search revealed an 'alarming display of medieval weapons', as described by Judge Simon Drew KC, alongside several knives. During police interviews, Mahmood admitted to writing the posts and owning the weapons but denied being a terrorist.
The court was told that Mahmood, who had over 27,000 followers on TikTok, had asked another user to send him the bomb-making instructional video via a messaging app.
Sentencing and Police Warning
Following a week-long trial at Birmingham Crown Court last September, Mahmood was found guilty of possessing a document containing information of use to a terrorist. He was sentenced on Thursday, January 15, 2026.
While there was no evidence of plans for a specific attack, the judge noted that ball bearings found in his bedroom suggested Mahmood was 'at least contemplating assembling such a device'. Judge Drew KC said there was a 'significant risk' of further offences and that Mahmood had shown a 'high level of interest in, and support for, prohibited terrorist organisations'.
Detective Chief Superintendent Alison Hurst, head of Counter Terrorism Policing in the West Midlands, said: 'Videos found on Mahmood’s phone were dangerous and showed extreme violence. Anyone who sees or hears something that could be terrorist-related should act on their instincts.'
The public is urged to report concerns in confidence by calling 0800 789 321, visiting gov.uk/ACT, or dialling 999 in an emergency.
