Middlesbrough Teen Sentenced for Terrorism Offences

A nineteen-year-old man from Middlesborough, who amassed terrorist material and shared a video of himself ‘triggering’ an imitation suicide vest, has been imprisoned for 9-and-a-half years, following an investigation by Counter Terrorism Policing North East.

Mohammed Khalil Nadir (18/08/2007) of Clough Close, was sentenced at Leeds Crown Court today (Tuesday, September 1) after he was found guilty of possessing articles for a terrorist purpose and disseminating terrorist publications during his trial in June.

The jury heard how Nadir had researched the mock explosive vest worn during the Heaton Park Synagogue attack, before placing an order for a similar vest hours later. On the day the vest was delivered, Nadir added 500 steel ball bearings to his online shopping basket. He recorded a video of himself wearing the vest, modified with a fake wire and trigger, and overlaid the sound of an explosion before sharing it on Telegram.

In the searches that followed Nadir’s arrest in October 2025, officers found the weighted vest in his wardrobe, handwritten texts promoting martyrdom operations, and a wealth of terrorist material on his mobile devices. This material included Daesh propaganda videos, and texts calling for the killing of ‘disbelievers’.
