Following the incident on Wednesday where 2 Jewish men were attacked, but also other evidence available to the Police and Security Services, the threat level has been raised which means an attack is highly likely in the next six months.
NB: As we’ve advised, consider this beyond terrorism, as the incidents may trigger those who do not fit the ‘Prevent’ model but are potentially autistic, and/or mentally ill, and/or a lone person obsessed with violence.
What “Severe” Means
The UK uses five threat levels to inform the public and guide the response of police and security services. Severe is the second-highest level:
| Level | Definition |
| CRITICAL | An attack is highly likely in the near future |
| SEVERE | An attack is highly likely |
| SUBSTANTIAL | An attack is likely |
| MODERATE | An attack is possible but not likely |
| LOW | An attack is highly unlikely |
The decision was made by the Joint Terrorism Analysis Centre (JTAC) on the 30th April 2026.
Advice remains as: “Be alert, not alarmed.”
We may see and review actions as follows:
* Visible Police Presence: You may notice more officers in public spaces, particularly around transport hubs, religious institutions, and large events.
DS says: It is the season of outdoor events – hopefully! Do you make sure you liaise with your Police beat team to see if they can attend too?
* Increased Vigilance: The public is encouraged to report any suspicious activity or concerns to the police via the Anti-Terrorist Hotline (0800 789 321) or through the Action Counters Terrorism (ACT) website.
DS says: See our BOLD type comment above as other concerns may need to take another route.
* Security Reviews: Large public events (such as marches or festivals) are currently undergoing enhanced security reviews to ensure public safety.
DS says: Do review your risk assessments to ensure you have content on aspects such as knowledge of attendees, bag contents, etc.at drop off and pick up and also at any of your events.
