A police film that provides advice on the steps to take to keep safe in the event of a terrorist attack has been released to the public.
After recent terrorist events around the world, the UK is considered as ‘Severe’, meaning an attack is highly likely.
There were calls this week for gunfire detectors to be installed at the Westfield shopping centre .
The four minute film, Stay Safe: Firearms and Weapons Attack sets out three key steps for keeping safe.
The film and accompanying leaflet advise that if you are caught up in an incident to ‘run, hide and tell’ which police say can be applied to many places and situations.
Speaking on behalf of National Counter Terrorism Policing, Deputy Assistant Commissioner, Neil Basu said: “The public should not be alarmed by this step.
“While the general level of threat to the UK is Severe, the probability of being caught up in a firearms or weapons attack is very, very small.
“However, it is important the public know what to do in the event of getting caught up in such an incident.
"Our advice has already been issued to tens of thousands of people during police-led security training sessions but it is only responsible that we issues this public safety guidance more widely.
"We know that from case studies and the testimony of people who have survived attacks that the advice given in the film has saved lives."
'You are our eyes and ears'
The advice outlines a 'run, hide and tell' method, detailing step by step the different methods of surviving a possible attack in various scenarios.
Mr Basu continued: “With the threat level remaining at a high level, the police and security service continue to operate at a heightened state of readiness - we are working on hundreds of investigations and making an arrest a day.
"However, it is only with the ongoing support of communities that we can defeat terrorism - you are our eyes and ears so please be alert, but not alarmed.
"We are asking everyone to remain vigilant and report any suspicious behaviour or activity to the confidential Anti-Terrorist Hotline on 0800 789321 or, in an emergency, 999."
