Appeal for the identity of sick Hammers fan

This is an appeal to anyone who knows the Hammers fan pictured below or any details or contact details for his family or you know where he lives. The West Ham supporter is currently in intensive care unit and the hospital need to desperately contact his family as soon as possible so have asked for the help of West Ham fans in an attempt to contact his family.

Known as West Ham Dave or Dagenham Dave. Possibly from East Ham area and often seen in Queens pub where he collected glasses. He is thought to have a brother and a sister.

Update: His real name David Avis but the hospital are keen to contact relatives.
