“We are focusing our activity in the Seaton Park, Balgownie, Grandholm, Tillydrone and Old Aberdeen areas in particular and I would urge anybody who thinks they have seen David or has any information as to his whereabouts to contact us.
“Additionally, I would ask that anybody who lives in these areas to check sheds, outbuildings or gardens for anything which may assist us in our enquiries”
