Chief Inspector Scott Carlin at Dumbarton Police Station said:
“We do not believe that Sophie has any money or a mobile phone with her and know that she was very upset on Saturday when she was last seen and didn’t say where she was going."
“Police, as well as her family and friends just want to know that she is safe and well and urge anyone who has seen her or anyone who knows of her present whereabouts to contact us immediately."
“Sophie is originally from the Bo’ness area and we have been liaising with British Transport Police, bus companies and taxi companies in case she has made her way back there. So far we have received a number of unconfirmed sightings and are following up information that has been provided to us."
“I also appeal directly to Sophie to make contact with either her family and friends or police to let us know that she is safe.”
Anyone with information that could assist in tracing Sophie is asked to contact police at Dumbarton via 101 quoting Incident number 2506 of Saturday 20 October 2018.
