The NHS Blood and Transplant Service (NHSBT) says it has been inundated with offers to donate blood following Monday's attack.
Manchester Blood banks are turning away some prospective donors after an “overwhelming” outpouring of offers to donate wake of Monday’s terrorist attack in Manchester.
The NHSBT service made a public appeal for potential donors this morning. Shortly afterward large queues developed at most of Manchester Blood Donations Centres as people are desperate to help in anyway they can.
Mike Stredder, Director of Blood Donation at NHSBT said: "We are responding to last nights events in Manchester. Our thoughts are with the people affected by this tragic incident.
"Thank you for thinking of giving blood at this time. We do have all the blood required for hospital patients at the present time.
"If you have an appointment to give blood in the next few days, please do your best to keep it, particularly if you are blood group O negative."
Those who don’t have appointments are encouraged to register with the NHS Blood and Transplant database and become a future donor.
