Police have issued a fresh appeal for information about a girl missing for a week as they warned about “misinformation online” suggesting she has been found.

Eva Brown was last seen leaving a family member’s home in Winchburgh, West Lothian, on Friday August 9.

She said she was going to stay with friends in Glasgow, but has not been in contact since Sunday August 11.

Schools in much of Scotland went back this week, and detectives said they are “extremely concerned” for Eva’s wellbeing, as “extensive searches” continue.

Two photographs have been released of Eva, including a school portrait and another showing her dressed in a black leather jacket.

Eva is white, 5ft 6in and of slim build with medium-length brown hair.

She was wearing a grey top, grey joggers and black trainers when she was last seen, and was carrying a black backpack.

Eva is said to have links to Whitley Bay, Tyne and Wear, as well as Mallaig in the Highlands, Aberdeen, and Glasgow city centre.

Inspector Richard Homewood said: “As time passes, we continue to be extremely concerned for 14-year-old Eva’s safety and wellbeing.

“We are aware of misinformation online that Eva has been traced. She has not. She is still missing.

“Extensive searches and inquiries are ongoing to trace her as soon as possible to ensure that she is safe and well.

“Eva is known to frequent Glasgow city centre, Aberdeen, Mallaig, West Lothian and Whitley Bay in Northumbria and we are liaising with colleagues in these areas.

“I would urge anyone who has seen her or who has any information on her whereabouts to contact us as soon as possible.

“We would also ask Eva, if she sees this appeal, to please make contact with us to let us know you are safe.

“Anyone with information is asked to contact Police Scotland on 101, quoting incident number 1258 of Tuesday August 13.”
