High street retailers are being asked to draw up 60-second security plans in the lead up to Black Friday, as part of the Counter Terrorism Policing winter advertising campaign.
The campaign, launched on 19 November, calls for busy retailers to create contingency plans to improve their reactions to emergency situations.
Plans should consider who is the primary decision maker, when to evacuate, when to lock down and how to communicate with officials during an emergency situation.
The initiative is an effort to avoid a similar panic to that of Black Friday last year when false reports of a terror attack in Oxford Circus caused a stampede at rush hour.
Businesses are also encouraged to sign up to Act Awareness, an online training scheme developed in partnership with Marks & Spencer. The 45-minute course is designed to help the industry better understand and protect against current terrorism threats.
Shoppers are encouraged to remain vigilant and collaborate with retailers in minimising the chance of attacks during the festive period.
