New CCTV footage has been released in the bid to trace a missing Aberdeen teen.
Liam Smith was last seen in Aberdeen on Saturday.
He was spotted boarding a bus heading towards Banchory and Lumphanan and Union Square.
The 16-year-old Westhill Academy pupil is understood to have bought a ticket to Raemoir Road in Banchory with officers focusing their search on this area today.
The new footage, captured at Union Square, shows Liam shortly before he boarded the 202 Stagecoach bus.
Chief Inspector Martin Mackay said: “Our last confirmed sighting of Liam is at the bus station in Aberdeen on Saturday November 17, and we are continuing to urge anyone who was in that area or who was on the 1.11pm 202 bus to Deeside to contact us.
“The bus would have made a number of stops at towns and villages including Cults, Peterculter, Drumoak, Crathes and Banchory and we are urging anyone who may have got on the bus at any of these stops or was perhaps meeting someone off the bus and saw Liam to contact us.
“It is hoped that by releasing the moving images of Liam which shows his distinct gait that this helps jog people’s memories and think about if they saw him on Saturday.
“Saturday was a busy day in sport with the Scotland v South Africa rugby match and also Scotland playing Albania in the UEFA Nations League.
“We would hope that people may have an enhanced memory of their plans that day and if they were travelling in or out of Aberdeen City Centre they might remember seeing Liam.
“We know Liam is interested in sport and has played football with Westdyke, Banks o’Dee, Dyce Boys Club, Culter Boys Club and Glentanar.
“He is also a member of PureGym. It might have been that Liam was planning to meet friends or spoke to someone about the upcoming games and we would urge anyone who was in touch with him to contact police.”
