Police have renewed their appeals for information to find 62-year-old Norman Race, who has been missing for more than two months.
He was last seen speaking to a friend on August 8, when he said he was ‘camping up north’.
Now police believe he may be in the Kent area and have asked Kent Police to make enquiries.
Mr Race, who was reported missing by his family on September 4, is 5ft 7ins tall, slim, with blue eyes, short hair and usually has a beard.
He lives alone in George Street in the Old Town, works in the building trade on a self-employed basis, and enjoys cycling. His cycle, which is also missing, usually has a small trailer attached.
Inspector Paul Phelps said: “Mr Race could be anyway in the region or even the country due to his love of cycling. He does often cycle long distances and lives an independent life.
“He is classified as low risk and although he isn’t deemed to be a danger to himself or others, his disappearance is causing lots of heartache and concern to his family.
“We are still keen to find him just to ensure that he is safe and well. Anyone who has any information as to where he might be, and Mr Race himself, are asked to contact Sussex Police on 101 quoting serial 1740 of 4/9.”
