Amelia Arnold, 19, went missing from her home in Hadrian's Walk, Stevenage, Hertfordshire, on Wednesday.

Her boyfriend Jack Wall, 22, with whom she lived, was arrested on suspicion of murder after he handed himself into police on Sunday. He remains in custody, Hertfordshire Police said.

A body, which police believe to be that of Miss Arnold, was found in woods in Hatfield on Sunday. Formal identification and post-mortem tests are yet to be carried out, a Hertfordshire Police spokeswoman said.

Miss Arnold's family have been informed and are being supported by specialist officers, the spokeswoman added.
