Amber went missing from her home on Bosworth Street at about 5.30pm on Saturday after a minor row with her mum Kelly and stepdad Danny over chores.
Police and local residents organised searches in a bid to find the 13-year-old, with posters being displayed around the area.
A press conference was held on Tuesday morning in which Kelly and Danny made an emotional plea for Amber to come home.
But on Tuesday night, a body, believed to be Amber, was discovered in undergrowth on Westfield Lane.
Formal identification and a post-mortem is due to take place later today (Wednesday).
