A teenager from Oxfordshire has been charged with terrorism offences after counter-terrorism officers discovered an extensive weapons cache at his family residence.

The 16-year-old, from Didcot, appeared before Westminster Magistrates’ Court where Chief Magistrate Paul Goldspring ordered his detention in secure accommodation designated for young defendants.

Prosecutors outlined allegations that the youth had amassed a collection of bladed weapons, including 17 knives and machetes, along with swords and a knuckleduster stored in his bedroom.

Officers reportedly uncovered homemade explosive devices and a suicide vest during the search of the property on March 12.

The accused, who reportedly converted to Islam during his teenage years, faces charges of distributing terrorist material, including videos depicting Islamic State operations and footage of the Paris attacks, which were allegedly sent to a family member.

Further allegations involve sharing battlefield videos showing militant activities.

Additional counts relate to possession of extremist publications, specifically an IS magazine titled Inspire 1 and an instructional document known as 100 Deadly Skills.

The teenager is also accused of failing to provide access to his mobile phone while detained.

Through his legal representative, the accused entered not guilty pleas to all eight charges.

The case is listed for further proceedings at the Central Criminal Court on April 17.

The prosecution cites multiple offences under terrorism legislation, including dissemination of terrorist publications contrary to the Terrorism Act 2006, possession of articles for terrorist purposes under the Terrorism Act 2000, and possessing material useful for terrorism.

A further charge relates to non-compliance with regulatory notice requirements.

The individual was initially taken into custody on March 12 and formally charged five days later.

Legal restrictions prevent identification of the defendant due to his age.
