Following an assessment by Joint Terrorism Analysis Centre (JTAC), the Prime Minister announced that the UK threat level from international terrorism has reduced from critical to severe, meaning an attack is highly likely.

Following the announcement, Chief Constable Andy Cooke said: "Since Friday's attack at Parsons Green station in London, and in response to the heightened threat level, members of the public have seen an increased policing and security presence at key sites and other crowded places across Merseyside to help protect our communities.

"The Prime Minister has indicated today that the threat level has reduced from critical to severe. I want our communities to be reassured that the safety of our communities is paramount and we are continually reviewing our resources part of a range of measures to reassure communities and make sure we are all well protected at these times of high alert.

"People will continue to see firearms officers patrolling Liverpool and other locations in Merseyside for the foreseeable future, and we will continue to work with event organisers, transport companies and other partners to ensure appropriate security measures are in place.

"We urge the public to remain aware and alert but not alarmed - the police service and our partners are doing everything we can to help protect the security of our communities, public institutions, critical national infrastructure, and businesses and places of interest.

"Our security measures and activities are under constant review to reflect where the threats exist and the level of threat we are facing.

"Be vigilant. If you suspect it, report it. Nobody is better placed to detect something that is out of place in their communities than the people living in them.

"We would encourage you if you do see any suspicious activity, to call the Anti-Terrorist Hotline on 0800 789 321, or in an emergency the public should always call 999. For further information about reporting suspicious behaviour visit https://act.campaign.gov.uk

"If you get caught up in the rare event of a weapons attack we urge you to follow the Run, Tell, Hide advice (www.nactso.gov.uk).

"Terrorists seek to create discord, distrust and fear. The police stand together with all communities in the UK and we will take action against any criminal behaviour which seeks to undermine society, especially where crimes are motivated by hate.

"Communities defeat terrorism, which is why we need to work together, the public and police. We depend on information from the public, who can be our eyes and ears, to keep us all safe.

"Acts of terrorism and hate crimes are committed by a small minority of people and are not representative of the public at large. At times like this it is vital our communities pull together and support eachother. Everybody, from law enforcement, to businesses, to the general public, has a role to play in keeping the UK safe from terrorism."
