Fears are mounting for the welfare of a West Sussex man who went for a long walk and did not return.

Alec Walter Allen, 38, from Barnham, near Bognor, was last seen in the Church Norton area, close to Pagham Harbour nature reserve, on October 11.

He set out on one of his regular long walks and was reported missing by a member of family the next day.

A Sussex Police spokesman said: "He will walk long distances in country areas on a regular basis and does this without informing family and friends where he his visiting."

Mr Allen is white, 5 ft 6in to 5ft 7in tall and muscular, with a clear complexion and blue eyes.

His hair is short, fair and greying. He has a beard and wears a distinctive black and white bandanna.

Police have appealed for members of the public to report any sightings of persons fitting this description, particularly in country areas in and around the nature reserve.
