Liam Smith: Family of missing Aberdeen teenager 'clinging to hope'
The mother of a 16-year-old missing from Aberdeen since Saturday has said his family are "clinging to hope".
Liam Smith caught the 202 Stagecoach bus from Aberdeen on Saturday afternoon at 13:11.
It is understood he bought a ticket to Banchory.
His mother Alix Smith said: "As each day passes we are becoming more and more desperate to find Liam. We are literally clinging to the hope that he is out there somewhere taking shelter."
In a statement issued through police, she added: "Not knowing where Liam is is just so painful for us and we just want to find him safe.
"Thank you to everyone who has shared the social media appeals, to those people who have phoned the police with potential sightings of Liam, and to the many comments and kind words that have been posted.
"We are really grateful for all of the help and it really does bring us comfort to know that so many people are thinking of Liam and are trying to help us find him."
'Not in trouble'
She said: "I would appeal again to anyone who may have seen Liam to come forward as it's now been five days since we last saw him. Are you friends with Liam and heard from him in the past few days? Has he ever mentioned a particular spot to you that he might want to go?
"Please know that he is not in trouble - we just want him home."
Ch Insp Martin Mackay said: "We are still trying to establish why Liam has disappeared and what made him travel in this particular direction.
"Please be assured that countless lines of inquiry are being pursued and we are keeping in close contact with the family in relation to updates.
"We cannot publicise every line of inquiry we are pursuing for numerous reasons but be assured that we are doing everything we possibly can."
An image of a camouflage backpack of the type that the teenager had when he went missing was earlier released by police.
When last seen, Liam - who is about 6ft 4in tall - was wearing a dark top, blue jeans and Nike Air Max trainers.
