MERSEYSIDE'S Chief Constable has said a highly-visible police presence is now in place after the Manchester arena explosion and Prime Minister's announcement that the UK threat level from international terrorism is now critical.

In a statement today Chief Cons Andy Cooke said: "The level of threat is complex and together with our partners the police service is doing everything we can across the country to prevent attacks and to protect our communities.

"I would like to take this opportunity to reassure communities across Merseyside that their safety is paramount and we must all remain vigilant.

"We have reviewed our resources as part of a range of measures to reassure communities and make sure we are well protected during these times of high alert.

"In response to this heightened threat members of the public will see an increased policing and security presence at key sites, such as train stations and other crowded places to help protect our communities.

"Officers from our event planning team and protective security experts will be working together with event organisers to ensure that venues have appropriate security measures in place for events planned in the near future.

"As a precautionary measure we have increased the number of officers on duty to provide a highly visible, reassurance presence - both overtly armed and unarmed - across the country for as long as is needed.

"We urge the public to remain 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.

"The latest guidance on recognising the terrorist threat and remaining vigilant can be accessed via www.nactso.gov.uk

"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 act.campaign.gov.uk/

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

"Terrorists want to create discord, distrust and to create 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 at times like this are 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 that all communities pull together and support each other.

"Everybody, from law enforcement, to businesses, to the general public, has a role to play in keeping the UK safe from terrorism".
