Met Police Warning After Teen Jailed for Weapon Building from Videos

Metropolitan Police Issue Stern Warning to Parents Following Teenager's Weapon-Building Conviction

The Metropolitan Police have issued a stark warning to parents across London after a teenager obsessed with firearms and explosives was sentenced to four years in prison. The case highlights the alarming ease with which young people can access dangerous online content that leads to criminal activity.

Hundreds of Hours Spent Watching Weapon Tutorials

Sakhile Ntsele, 19, became dangerously fixated with weapons and would spend entire days in his south London bedroom watching online tutorials about constructing firearms and developing explosive devices. Police investigators discovered he had devoted "hundreds of hours" to studying these dangerous materials before attempting to build the weapons himself.

Detective Inspector Raymond Sekalongo stated: "Ntsele's obsession with firearms was extreme. He dedicated countless hours to watching instructional videos about weapon construction and explosive development from his bedroom. While we cannot speculate about his ultimate intentions, the weapons he manufactured had clear potential to cause serious injury or death."

Cache of Homemade Weapons Discovered

The full extent of Ntsele's activities came to light on October 27, 2024, when police responded to reports of a domestic assault at his residence. Officers learned that Ntsele had squirted antibacterial cleaner into a family member's face before attempting to attack them with a homemade sword.

During a subsequent search of his bedroom with a firearms recovery dog, police uncovered:

  • Seven improvised explosive devices
  • Five homemade firearms
  • Various ammunition components

Pattern of Weapon Obsession Uncovered

Further investigation revealed Ntsele had first attracted police attention at age 14 in December 2021, when he was arrested with 55 rounds of ammunition—some modified by inserting nails into cartridges. Although that case was discontinued in March 2023 due to insufficient evidence, detectives reopened it following his 2024 arrest.

Analysis of Ntsele's phone revealed an intense preoccupation with weapons, including:

  • Extensive search history focused on weapon construction
  • Hundreds of hours watching tutorials on shotgun shell production and homemade gun building
  • Use of a relative's credit card to purchase materials like steel balls and potassium nitrate
  • Employment of pseudonyms to avoid detection during purchases

In May 2024, Ntsele sent a friend videos showcasing a functional firearm he had constructed from wooden panels and iron pipes. Subsequent testing confirmed the weapon was operational and capable of inflicting serious harm.

Legal Consequences and Police Warning

Ntsele pleaded guilty to possession of ammunition without a certificate and five counts of possessing a firearm without certification. Following an 11-day trial, he was additionally found guilty of eight counts of manufacturing explosive substances for unlawful purposes.

The court sentenced him to four years imprisonment with an extended five-year licence period following his release.

Detective Inspector Sekalongo emphasized: "This case demonstrates how readily accessible dangerous and influential material is to children online. While we aim to avoid unnecessary alarm, we strongly urge all parents to maintain awareness of their children's online activities. Vigilance can prevent young people from entering dangerous spaces where they might be influenced toward criminal behavior."

The Metropolitan Police continue to emphasize the importance of parental supervision in digital spaces, particularly as online platforms make specialized knowledge about weapon construction increasingly available to impressionable young audiences.
