The family of a man who has disappeared from his Preston home have made a desperate appeal for information.
Martin Lucas, 51, has not been seen since he left his flat in Fishergate, with just the clothes he was wearing, overnight on March 21.
Martin, who works at the Inland Revenue in Preston, also has family links in London and spent several years studying and living in Lancaster.
His brother, Peter Lucas, 50, says it is “extremely out of character” for Martin to be away from home for so long and has been in contact with local birdwatching, poetry and table tennis groups in a desperate bid for information.
He says: “I last saw him on the Friday evening when I stayed at his house. He has a mental health condition which makes him anxious and suffers panic attacks.
“He asked me to go and spend the night with him as he was getting increasingly anxious and he went to bed at around 10pm.”
Peter, who also lives in central Preston, says he heard his brother moving around during the night but assumed he was getting a drink of water or visiting the bathroom.
When he woke the following morning he discovered his brother had left the flat but his keys were in the door and he had not taken his wallet, outdoor coat or any other belongings.
Martin has lived in Preston for 13 years and has a phD in Japanese poetry. He has many friends in the city through his hobbies, which also include table tennis and birdwatching.
Peter says the family are “worried sick” and urges anyone who knows anything about his brother’s movements in the days following his disappearance to contact the police.
Officers are scouring CCTV for clues as to where Martin may have gone but have not yet found any sightings.
Martin may be wearing walking-type clothing such as a fleece or waterproof jacket and jeans or tracksuit bottoms. He has short, light brown hair, is approximately six feet tall and is of medium build.
