A police spokesman said last night: "Amber's family has been informed and we ask that the media respect their privacy at this difficult time.
Police thanked all who had helped in the search, particularly the Mansfield community.
Amber's parents had earlier issued an emotional plea for her to return.
Her mother and stepfather broke down in tears as they spoke at a police press conference, saying her disappearance was out of character.Kelly and Danny Peat said she walked out after refusing to clean a cool box used to store food during a holiday to Cornwall after the family had returned on Friday.
Mr Peat said: "We had just all had a brilliant holiday. It's just not right. She had a fantastic time, never stopped laughing with all of us together."
Ms Peat said: "We were in the living room and I heard the front door slam."
She went on: "I heard the door and when I went out I couldn't see her anywhere. She had just gone."
She said Amber was not in contact with her natural father, who lives in Scotland.
During the press conference Superintendent Matt McFarlane said Amber's disappearance was "totally out of character".
