Sussex Police are becoming increasingly concerned over the welfare of a 77-year-old man who has gone missing from Seaford.
Richard John Wise was last seen as 3pm on Sunday 29th December and is thought to be disappeared between then and 8pm when he left the house.
Mr Wise is unsteady on his feet, usually walking with the aid of a stick, and has mental health issues.
He has not been eating or drinking and has been prescribed anti-depressants and pain-killers which he needs to take regularly.
Inspector Philip Hogan, of Sussex Police said: "Richard's family are very worried because it is out of character for him to leave home on his own and without giving any indication of where he is going.
"The weather conditions are poor and Richard's health will deteriorate quickly unless he can be found."
Anyone with information should call 101.
