Two people who could hold the key in tracing a missing Aberdeen schoolboy’s movements have still to come forward, police have said.
Liam Smith, 16, has now been missing for 13 days and police have been leading a massive search operation.
Officers were searching Crathes and Banchory yesterday and searches were to continue today.
The Westhill Academy pupil was last seen boarding a Stagecoach 202 Deeside-bound bus at Union Square bus station in Aberdeen at 1.11pm on November 17.
Police have said the bus was very busy and most passengers have come forward to tell officers their experience of that journey.
One passenger told police they believe Liam got off at Crathes – one location of the search operation – but he bought a ticket to Banchory. The onboard CCTV was not working and so was unable to indicate where Liam got off.
A week ago today, Chief Inspector Martin Mackay made a direct appeal to two passengers who bought adult fares to the same Banchory stop as Liam.
They have yet to make themselves known to police and a Police Scotland spokeswoman said the appeal still stands.
Ch Insp Mackay said: “I wish to appeal for two people who got on the same Stagecoach 202 bus as Liam, but this time from outside the Run 4 It shop on Holburn Street.
“These two people purchased a ticket for Banchory and we believed they carried on through the duration of that journey to the Banchory area.
“I’m asking them to come forward.
“They might not think they have information that can help.
“But any information at all about how he was on the bus or where he left the bus will assist us in confirming the last sighting.”
Liam is white, 6ft 4in tall and of a slim build.
He has short brown hair and when he was last seen he was wearing a dark top, blue jeans and Nike Air Max trainers.
Liam was carrying a camouflage North Face bag.
Call police with information on 101 quoting reference 1302 of November 18.
