Malicious threats include actions like terrorism and organised crime, and details are often sensitive. While attacks in the UK are rare, recent events in Manchester and London highlight the very real threat faced in the UK.

Terrorism Threat Levels 

Terrorism threat levels indicate the likelihood of a terrorist attack in the UK. There are 5 categories at which the threat levels could be set:  

• LOW – an attack is highly unlikely  
• MODERATE – an attack is possible, but not likely  
• SUBSTANTIAL – an attack is likely  
• SEVERE – an attack is highly likely  
• CRITICAL – an attack is highly likely in the near future 

 This is the Current National Threat Level.

Reporting Suspicious Activity 

Members of the public should always remain alert to the danger of terrorism and report any suspicious activity. 

• Police – 999 
• Anti-terrorist hotline: 0800 789 321.  
• British Transport Police: 0800 40 50 40, or text 61016 
• Report possible terrorist or extremist activity | Action Counters Terrorism – Report possible terrorist or extremist activity 
• If your information does not relate to an imminent threat, you can also contact MI5.

Remember: If you are faced with the threat of an incident follow these simple steps:

• Hide. It’s better to hide than to confront. Remember to turn your phone to silent and turn off vibrate. Barricade yourself in if you can. Then finally and only when it’s safe to do so…
• Tell the police by calling 999
