Security Advice and Information

A crowd of people

The threat from terrorism is real and serious and we have seen that terrorists can strike at any time and any place without warning.

Currently the threat level to the United Kingdom from international terrorism is at Severe - this means that a terrorist attack is highly likely.

The threat to Great Britain from Northern Irish terrorism is Moderate - this means that a terrorist attack is possible but not likely.

Our overriding priority is to keep the public safe, by working together with all our communities.

Policing operations and contingency planning remain under constant review and a wide range of overt and covert tactics will continue to be used in London.

We continue to urge the public to remain vigilant and aware and to report any suspicious behaviour which may be terrorist-related to police.

For more information on the current threat level, visit the Home Office website.

What can I do as someone who works in London?

We need the help and support of individuals and organisations across London to maintain the safety and security of buildings, businesses, areas or neighbourhoods.

We recognise that you are the experts in your workplace and you are ideally placed to spot when something is amiss. In this period of heightened alert, it is vital to remain vigilant, trust your instincts and report possible reconnaissance to the police.

Crowded places, economic, government, travel, military, aviation, and iconic sites are all seen as potential targets for terrorists. All of these are to be found in London.

Examples of suspicious behaviour include:

  • People in stationary vehicles watching a building or structure, for no apparent reason.
  • Vehicles moving slowly near public buildings, structures or bridges, or parked in suspicious circumstances.
  • People using recording equipment, including camera phones, or seen making notes or sketches of security details for no apparent reason.
  • Someone paying close attention to specific entry and exit points; stairwells, hallways, fire escapes for no apparent reason.
  • People loitering at or near premises for long periods, watching patrons, for no apparent reason.
  • People asking detailed or unusual questions about buildings and business operations, facilities (such as room layouts), security or parking for no apparent reason.
  • Members of the public in offices and ‘off limits’ areas, plant rooms and similar locations.

It may be nothing, but if you see or hear anything that could be terrorist-related trust your instincts and call the Anti-Terrorist Hotline on 0800 789 321.

Our specially trained officers will take it from there.

In an emergency call 999.

Where can my organisation or business go to get security advice?

Your local Safer Neighbourhoods Team can provide advice and information.

In addition, specialist officers from the MPS regularly carry out briefings for the business community to help raise awareness of security issues.

Project Griffin host events for those people responsible for the safety and security of workplaces in London. For more information visit the Project Griffin website, the link to which is available in the related links section.

Operation Fairway delivers counter-terrorism briefing to raise awareness of suspicious activity and encourage reporting to the Anti-Terrorist Hotline. For more information email the Fairway Team. Their contact details can be found in the contacts section.

Counter Terrorism Security Advisers identify and assess local critical sites within their force area that may be vulnerable to terrorist or extremist attack, then devise and develop appropriate protective security plans to minimise impact on that site and the surrounding community. For more information email the CTSA. Their contact details can be found in the contacts section.
