Woodland search for missing Aberdeen teenager Liam Smith
Specialist police teams looking for missing Aberdeen teenager Liam Smith have been searching farmland, woodland and areas of water in the Crathes area.
Officers and dog teams were joined in the hunt by Aberdeen and Braemar Mountain Rescue members eight days after the 16-year-old was last seen.
Road patrols and a dashcam footage appeal have also been made.
Liam caught the 202 Stagecoach bus from Aberdeen last Saturday and is thought to have bought a ticket to Banchory.
Police believe the teenager may have got off in the town or one stop before in Crathes.
Large matrix signs have been put up on roads leading into Crathes asking members of the public if they have seen Liam.
It follows a video appeal by Scotland football manager Alex McLeish in a bid to find new information.
When last seen, Liam - who is 6ft 4in tall - was wearing a dark top and blue jeans. He had a camouflage backpack.
He did not have a mobile phone with him.
Ch Insp Martin Mackay said: "We are very grateful for the many messages of support for both Liam's family and the police inquiry and the suggestions we have received. All information passed to us will be followed up."
He added: "We don't know where Liam was intending on going last Saturday and the Crathes and Banchory areas are vast and include challenging terrain.
"Despite searches already carried out, Liam is still missing and we are continuing to urge anyone with information to contact police."
