Despite extensive enquiries and leads followed up by police officers over the years, Andrew has never been traced.
His health records shared have been shared in a bid to trace his whereabouts but to no avail.
Detective Sergeant Andy Knowles said: "We remain committed in continuing to pursue and investigate any information that could lead to finding Andrew and would ask anyone who believes they know where he may be, or who may have seen him to please come forward.
"We have worked with Andrew’s family and we will continue to do so in an attempt to be able to provide the answers they understandably are desperate to have. His family have continuously appealed for information as to his location and to ensure his wellbeing and have a dedicated website with further information.
"Throughout the investigation we have also liaised with the Missing People charity regarding reported sightings of him. The charity also have a page on their website dedicated to Andrew.
“I would ask anyone, maybe new friends, neighbours or workmates, who believes they know a 25-year-old man that could be Andrew, but aren’t aware of his past beyond the last few years to please come forward.
"In addition, any professionals, including doctors, dentists or hospital staff who may have treated a 25-year-old man who has no records going back beyond the last 10 years, you could hold information that proves vital to locating Andrew and I would ask you to please make contact with police.
"And to Andrew, a personal appeal, please contact us, completely confidentially, and let us know you are safe and well and we can reassure your family you have come to no harm."
