Following the incident in Manchester, Merseyside Police's Chief Constable Andy Cooke said: "Our thoughts and sympathies are with everyone affected by the terrible events in Manchester last night.

"A number of people have tragically died and many more have been injured during what should actually have been a safe and enjoyable night out at a concert for young people and their families.

"Our colleagues at Greater Manchester Police and British Transport Police as well as those in the other emergency services have been working tirelessly since the incident to investigate what happened and protect the public and we will support them in every way we can.

"A number of officers from this force have travelled to Manchester to offer mutual aid to our colleagues and other officers have come into work having been off-duty to maintain a visible presence in our own communities.

"I understand that this attack will feel very close to home for many local people who will understandably be worried. So I would like to reassure everyone in Merseyside that their safety is paramount and there is currently no specific threat to any particular locations or areas here.

"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.

"Police officers will, as always, be asked to be vigilant and we will maintain a visible presence in and around key locations.

"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.

"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 confidential Anti-Terrorist Hotline on 0800 789 321 or call police on 101 immediately.

"An emergency number is available for those who are concerned about loved ones or anyone who may have been in the area - 0161 856 9400."
