Samuel was last seen speaking to police officers as part of a ‘routine check’ on Union Street, Glasgow, October 19, 2016.

He is known to sleep rough and has no fixed address despite living in Clydebank as recently as last summer.

Police have no firm leads but are currently investigating a possible sighting in Clydebank job centre at the beginning of January.

His heartbroken sister said: “On behalf of our whole family, I would like to appeal to anyone who has any information at all as to the whereabouts of our much-loved and missed Samuel.

“He is a son, grandson, brother, nephew, cousin, uncle and friend. And his disappearance has left a gaping void in all our hearts.

“If you are in contact with Samuel please let him know we only want him to get in touch so that we know that he is safe and well.

“He is no trouble at all.”

She added: “We will get you any help you need and look after you. You are not alone. You are sadly missed and I am sorry that you have suffered so much.

“You will never be on your own again. God bless you, my brother.”

Samuel is described as white, 5ft 3in all with a stocky build and has short brown hair.

Despite living a ‘chaotic’ lifestyle, the unemployed 28-year-old is in occasional contact with his family.

In a bid to trace him, police have carried out investigations across Scotland including in Renfrewshire, Dunbartonshire, Lanarkshire, Glasgow and Falkirk.

Samuel’s father, William, who lives in Kilwinning, reported his son missing in North Ayrshire.

Chief Inspector Brian Shaw, the area commander for North Ayrshire, re-issued their appeal for Samuel’s safe return.

He said: “At this moment in time our enquiries have taken us all across the country, and I make no exaggeration about that.

“Samuel is an individual who doesn’t reside in one place for too long. He doesn’t keep a permanent residence to date.

“Samuel has associates in, and his family descend from, the travelling community. Samuel has his own lifestyle and he chooses to live that lifestyle.

“At this stage, we have no information whatsoever that Samuel has come to harm through any criminality.”
