Norfolk police have compiled some FAQs on what the threat level being raised to critical means for people living in or visiting the county.

What does this mean specifically for Norfolk?

Norfolk remains a safe county and any additional policing is about providing a visible reassurance to the public.

Are military personnel being deployed in joint patrols with police officers across Norfolk?

Military personnel are not currently being deployed, but the threat assessment is continuously under review. We will be patrolling some of the key locations in the city and town centres as well as other places that have a high footfall. They will be carrying weapons and are there to provide reassurance whilst remaining approachable. We would encourage anyone with questions about what their role is to go and speak to them.

There are events coming up – are these safe to go to?

Our officers from the event planning team and protective security experts will be working with event organisers and the multi-agency Safety Advisory Groups to ensure that venues have appropriate security measures in place.

Will these events still go ahead now that the threat level has been raised?

Some public events may be subject to cancellation. Please contact your event organiser or check details online before attending large events such as sports matches and concerts.

What do I do if I'm going to one of these events?

Allow extra time in advance of attending public events as heightened security measures such as searches may be implemented. Please be patient while these important checks are made by a police officer or authorised security representative.

What is your advice to members of the public to keep safe?

Norfolk Police and our partners are doing everything we can to prevent an attack and to protect the public, but communities can take steps to help protect themselves. We urge the public to tune in to national/local news bulletins and to follow the @NorfolkPolice Twitter account for advice and information about keeping safe.

What do I do if there is a terrorist incident in Norfolk?

If you are caught up in a firearms or weapons attack we urge you to stay safe by following the 'RUN. HIDE. TELL.' advice.

If you come under attack we advise you to:

RUN, if you can;

HIDE, if you can't run;

TELL, when you can, the police what's happening.

The police can get help there quickly to stop the threat. Also tell others of the threat so they don't approach danger.

What do I do if I suspect someone is involved in terrorism?

We ask the public to remain calm but alert – if you see anything which causes you concern, then call the police immediately on 999 or the anti-Terrorist Hotline on 0800 789 321.

Look out for anything that seems out of place, we would rather investigate concerns which come to nothing, rather than hear an incident could have been prevented.

All information passed to the police through the anti-Terrorist Hotline is treated in the strictest of confidence. It is thoroughly analysed and researched by experienced officers before, and if, any police action is taken.
