Scotland manager Alex McLeish has issued a personal appeal to help find missing teenager Liam Smith.
The last recorded sighting of the Westhill Academy pupil was at Union Square in Aberdeen last Saturday, where he bought a ticket for Raemoir Road in Banchory at 1.11pm.
Since then police have ramped up the search for the teen, including using kayak teams to search the River Dee.
On Saturday, police released a video message from the Aberdeen FC legend.
The Gothenburg Great said: “This is an urgent appeal for anybody who knows the whereabouts of Liam Smith.
“Liam if you are watching this message please come home.
“Your mum Alix and your family are very anxious to see you return.”
Police confirmed on social media that they were aware of a reported sighting of Liam in Inverurie, however it was unclear whether there was any credence to this information.
Officers trying to track down the 16-year-old have been unable to confirm where Liam got off the Stagecoach bus 202 due to faulty camera equipment.
On Saturday, officers were in the shopping centre and adjacent bus station handing out leaflets and speaking to the public as concern grows for the teen.
They were also on board a number of 202 buses speaking to the drivers and passengers.
Specialist searches are ongoing in Deeside, with high visibility patrols in Crathes and Banchory, as well as an incident unit in the latter where the public can pass on any information.
Search helicopters and sniffer dogs scoured Lumphanan earlier this week following a report that the teen had been seen in the village, but officers later confirmed that this was not the case.
The huge search operation then relocated to Banchory, and attention has now shifted to Crathes after a fellow bus passenger told police they saw Liam leave the coach there.
Aberdeen and Braemar mountain rescue teams have been assisting police and officers have also appealed for dash cam footage.
Liam’s increasingly concerned family have been donated a drone by a local firm, to help in their own search for him.
Huge matrix boards are also displayed at the entrance to Banchory asking members of the public if they have seen Liam.
on Friday search teams explored Crathes while the force’s marine unit kayaked along the River Dee from Banchory to Aberdeen.
Liam bought a bottle of Lucozade, a packet of Jaffa Cakes and a bar of Dairy Milk chocolate before catching the bus and police have asked people who may have noticed litter from the items to get in touch.
Anyone with information should call police on 101.
