A new donor has been found for a London man who desperately needs a bone marrow transplant. Musician John Triteos, 31, from Highgate, thought his life was saved in February when doctors located a woman in America whose marrow matched his perfectly, but she refused to help. The new donor lives just a few miles from his home. John, who is seriously ill with leukaemia in the Royal Free Hospital, Hampstead, is due to receive the transplant next month.
