THE National Terrorism Threat Level has been lowered by the Prime Minister.

Earlier today Theresa May announced the threat level would be reduced from critical, the highest category, to severe.

Armed police and an increased number of unarmed officers will continue to patrol the Thames Valley throughout the Bank Holiday Weekend.

After Monday, May 29, the number of officers patrolling the region will reduce.

A Thames Valley Police spokesman warned a severe threat level meant an attack was still 'highly likely'.

"Along with our partners we continue to do everything we can to help protect our communities," they said.

"Our security measures and activities, including those for pre-planned events, remain under constant review.

"There remains no intelligence to suggest a specific threat to our communities within the Thames Valley area and we will continue to provide a visible policing presence across the Force area to provide reassurance to our communities.

"Communities defeat terrorism, we depend on information from the public, you are also our eyes and ears, and everyone can play their part in the effort to keep us safe.

"Please remain vigilant and report any suspicious behaviour or activity to the confidential Anti-Terrorist Hotline on 0800 789 321 or in an emergency call 999.

"In the rare event of a weapons attack occurring we urge you to follow the Run, Hide, Tell advice."

The terror threat level was increased to critical after a suicide bombing in Manchester killed 22 people, including children and teenagers, on Monday.
