Doctors have appealed for more information to help a man who cannot remember any details of his life including his name, age or where he is from.

"Robert'' was found in a Peterborough park early on 18 May and is thought to be in his 20s and possibly Eastern European.

Dr Manaan Kar-Ray, clinical director of acute care at Cambridgeshire and Peterborough NHS Trust, said Robert was distressed at not knowing who he really was.
