UPDATE: National security state raised - West Midlands Police response

Last night the national security state was raised to critical. This means that not only does an attack remain highly likely but a further attack may be imminent.

The prime minister also authorised support from the military alongside the police, known as Operation Temperer.

However at this stage there are no plans to deploy military officers in the West Midlands; therefore the public are unlikely to see military personnel on the streets.

Support from the military will instead free up armed officers from certain guarding duties to release officers across the UK to support the wider national response.

As soon as the prime minister made her announcement, we implemented our locally tailored plan, including keeping officers on duty. 

Assistant Chief Constable Alex Murray, said: "We are flexing our resources and increasing our presence at key sites, such as transport and other crowded places and we continue to review key events and entertainment venues. 

"At the moment, there is no plan for military personnel to be deployed in the West Midlands; however the public will notice an increase in the number of armed and unarmed officers. 

"While this is a precautionary measure, these highly visible patrols will continue for as long as is needed.

"You would expect us to do everything possible to prevent further attacks and keep you safe."

West Midlands Police and Crime Commissioner David Jamieson, said: "I am working with the Chief Constable to ensure that the additional armed resources are integrated into our capabilities to offer increased assurance and protection and protection to the public.

"People should continue to carry on with their lives as normal and not let those who seek to divide us to win. I ask people to continue to be vigilant and report suspicious activities to the police.

"West Midlands Police have shown their dedication and commitment in recent days and I'm sure they will continue to do so."

Please remain calm but alert. If you see anything that causes you concern, then let us know immediately, if you have suspicions about someone's behaviour call us.

Look out for anything that seems out of place, unusual or doesn't seem to fit in with day-to-day life.
