The Home Secretary has announced a decrease in the UK’s Terrorist Threat Level from Severe to Substantial.

Severe indicates that an attack is ‘highly likely’ whilst Substantial suggest that an attack is ‘likely.’

Threat levels in themselves do not require specific responses from the public. They are a tool for security practitioners working across different sectors of the Critical National Infrastructure (CNI) and the police to use in determining what protective security response may be required.

Police Scotland have responded by stating that there is nothing to suggest that there is any specific threat to Scotland but reminded people to remain vigilant.

Assistant Chief Constable Pat Campbell said: “At this time there is nothing to suggest that there is any specific threat to Scotland.

“However, I would remind the people of Scotland that they should remain vigilant and report any suspicious activity to Police Scotland.”

The Joint Terrorism Analysis Centre (JTAC) is the UK’s centre for the analysis and assessment of international terrorism and has responsibility for setting international terrorism threat levels.

Since 2006, information about the national threat level has been available on the MI5 and Home Office websites.
