Derbyshire Police have announced that Amanda Ditrichva has been located ‘safe and well’ in Derby.
A police statement thanked all who had assisted with the investigation.
The spokesperson said: “Amanda Ditrichva has been located safe and well in Derby.
“Thank you to all those who shared our appeal.”
Police had been searching for the missing teenage girl with Derbyshire connections, and particular links to two Derby suburbs.
Derbyshire officers reissued an appeal put out by Dyfed-Powys Police in Wales earlier today in a bid to find the school girl.
The 15-year-old was reported missing from the Church Stoke area of Powys and was last seen shortly before 9pm on Tuesday, May 18.
