More than 2,000 potential bone marrow donors have provided saliva samples at an event in Leicester, England. This is to help a teenage girl and a local policeman.
The teenage girl, Bethany Mickleburgh, who is 14, has been diagnosed with leukaemia for a third time, and needs a transplant. Leicester police Insp Rik Basra has appealed in October this year to find a fellow Asian donor.
The samples provided by the donors will determine whether they are bone marrow matches.
The Anthony Nolan Trust said it had recruited more potential donors at the event than ever before.
Jenner Large, from the trust, said: "Hopefully from this event, at some point, matches will be found and it will only help us save more lives."
The event took place at Welford Road, the Leicester Tigers rugby ground, on 12 November 2011, Saturday.
