Police have issued a fresh plea for help in trying to trace a man from Hove who has been missing for more than a month.
Richard Callan, 49, went missing on Saturday 27 September and has not been in touch with his family or friends since, Sussex Police said.
Mr Callan, of Waterloo Street, Hove, left work that day saying that he felt unwell but since then no one who knows him has seen him.
He was reported missing on Wednesday 15 October and since then officers have been trying to trace him.
PC Johanna Clarke: “There is nothing to suggest that anything has happened to Richard but we are becoming increasingly concerned for his welfare because it has been so long since he went missing.
“It is possible that he is sleeping rough in the city somewhere but we urgently need to find him to make sure he is ok.”
Anyone who has seen Mr Callan or knows where he may be is asked to phone Sussex Police on 101 or email 101@sussex.pnn.police.uk.
