The body of slain journalist Kim Wall was intentionally weighed down with a piece of metal, police in Denmark have said.

Ms Wall's headless, limbless torso was found on Monday and her identity confirmed on Wednesday.

The experienced foreign correspondent was allegedly killed on board a submarine owned by Danish inventor Peter Madsen, 46.

Police said a piece of metal was attached to her body "likely with the purpose to make it sink".

Mr Madsen told a court she Ms Wall, 30, died in an accident and that he "buried" her at sea, changing his previous statement that he dropped her off alive in Copenhagen. He denies killing her.

Ms Wall had been missing since the pair went out to sea aboard the 18m UC3 Nautilus craft on August 10. The submarine sank the next day and Mr Madsen was rescued.
