Police have launched an urgent appeal to locate a 14-year-old girl who has not attended school since January.
Millie Birley, from Sunderland, has not been seen since last month and Northumbria Police are desperate to track her down.
The force said that despite repeated attempts to contact her parents, the school failed to get a response.
Police were contacted two weeks later and attended the schoolgirl’s family home.
Officers were told by neighbours that the family may have moved from the area a week earlier, without informing their landlord or school authority.
Millie is believed to be travelling with her mum and dad but their whereabouts is not known.
Police are extremely keen to make contact with Millie and her family and say it is imperative that she or her parents report to their nearest police station as soon as possible.
Officers are also appealing to the public for help in locating the teen.
Millie’s family have links to the Scarborough and Hull areas but officers have not ruled out that they may currently be elsewhere.
A spokesperson said: "It is believed that Millie is travelling around various areas of the country in company with her parents.
"We are extremely keen to speak to Millie and her parents and it is imperative that they report to their nearest police station as soon as possible."
On Twitter, the force posted: "We are searching for missing teenager Millie Birley and need your help.
"The 14-year-old from Sunderland was reported absent from school in January. The teen’s absence continued and, despite repeated attempts to contact her parents, the school failed to get a response.
