London Bridge incident: Protective Security Advice

Following the attack in London Bridge, it is important that businesses remind their staff to stay alert and vigilant. The tragic events this year remind us that attacks can occur at any time or place without warning. Businesses are encouraged to review their security plans to ensure that the measures they should already have in place, are current and have been recently tested to ensure staff are prepared and confident. The London Bridge attack saw the use of a vehicle as a weapon and bladed weapons, however you should ensure that your planning and responses consider the full range or potential terrorist attack methodologies including IEDs (person borne, placed or vehicle) following the Manchester attack. The police and our partners continue to do everything we can to protect the security of our citizens, public institutions, critical national infrastructure, places and businesses. The public can expect to see additional police – both armed and unarmed officers – across London. In response to the ongoing threat the public will see an increased policing and security presence across the country at key sites, such as train stations and other crowded places to help protect communities.

Depending upon their responsibilities an effective security guard must be able to demonstrate they can respond effectively to a number of scenarios including:


Are your first aid kits and crisis incident kits (grab bags) checked regularly, complete and accessible? Link to citizenAid

Search Planning

Do you have plans to search your site to deal effectively with either bomb threats or for secreted threat items, and are your staff familiar with those plans? Do you have a person and vehicle, search and screening policy and plan that you can implement should there be a threat increase? Business as usual search and screen (looking for prohibited items) should, when done well, provide a very good capability to detect larger terrorist items concealed about the person
  • ensure the search and screening regime in place at the venue is done well
  • consider provisional search and screening on the approach or outside the venue, for example a visual check inside jackets and bags
  • ensure you maintain your search and patrol regime for the lifecycle of the event including prior to the commencement, during and post event
  • provide effective public address messaging of people as they approach, asking people to prepare for additional search and screening. This should reduce unacceptable delay
  • prior notification (at point of sale or media) of these extra security measures and encouraging people to arrive early, will smooth peaks and allow safe and effective searching


Have you reviewed your evacuation, invacuation and lockdown plans in response to terrorist attack?
