Croydon man who encouraged terrorism online jailed

A 60-year-old Croydon man, Paul Martin, was jailed after being convicted of encouraging terrorism for urging a violent uprising against the UK government in thousands of posts on a Telegram channel called The Resistance UK. Investigators said he posted about 16,000 messages in the 8,000-member group, promoted claims that Covid was a hoax and vaccines were poison, and encouraged people to obtain weapons and use crossbows, explosives and petrol bombs to carry out attacks. He was arrested at his home on 28 September 2021 and police seized a stun gun disguised as a torch, two crossbows with bolts, a large knife, air guns and drones. After a trial at the Old Bailey he was found guilty of encouragement of terrorism under the Terrorism Act 2006, acquitted of possessing articles for terrorist purposes under the Terrorism Act 2000, and had previously pleaded guilty to possessing a prohibited weapon. He was sentenced to three years and three months in prison.

About Sentinel

SENTINEL is a European project funded by the European Commission and led by the Security and Crisis Centre (SACC by EJC), the security arm of the European Jewish Congress. It brings together the International Centre for Counter-Terrorism (ICCT), national-level Jewish communities from Austria, Czech Republic, Hungary, Italy, and Spain, the European Union of Jewish Students, with the support of the Italian Carabinieri and the Police Presidium of the Czech Republic.

The project is designed to strengthen the protection of Jewish places of worship across the European Union through a coordinated set of activities over a three-year period.

SENTINEL will harness AI-enhanced open-source intelligence to monitor and assess current, emerging, and future threats. It will also equip Jewish communities with practical tools, including a mobile security application with a panic button and an interactive map built on real-time incident data.

Training and capacity-building are at the core of the project. These include scenario-based security exercises, crisis management seminars, and both in-person and online training sessions for community security trustees. SENTINEL will also organise EU-wide and local conferences to foster collaboration between Jewish communities, public authorities, and law enforcement agencies.

Complementing these efforts, national and local workshops will promote knowledge-sharing and preparedness, alongside pilot training programmes for law enforcement. A dedicated podcast series will help raise awareness by exploring threat assessments and potential responses.

With its wide-reaching and inclusive approach, SENTINEL will directly benefit to Jewish communities across 23 EU Member States, enhancing resilience, strengthening preparedness, and building long-term cooperation with law enforcement to meet today’s evolving security challenges.
