A 71-year-old man has gone missing from his home.

David Bigg was last seen at his home in Radlett just before 6pm on Thursday, August 2.

Police officers believe he may have travelled from Portsmouth to Brighton between August 3 and August 5.

He is described as white, of a slim build and with a grey beard.

He is bald on top with long grey hair at the back and sides.

Mr Bigg was last seen wearing a blue chequered shirt and khaki trousers.

He is known to walk with a limp and uses a walking stick.

It is believed he travelled from Radlett to St Albans before boarding a train to Portsmouth.

David also has links to the Bushey, Welwyn, Hatfield, Watford and Three Rivers areas in Hertfordshire.

Officers are growing increasingly concerned for his welfare.
