A self-professed psychic looking for missing Sydney girl Kiesha Abrahams visited a reserve in Doonside and discovered the torso of a woman.

Police revealed today that the psychic, a local woman whose name was not released, went to Nurragingy Reserve at Knox Road last night because she had a "hunch" that the missing six-year-old girl’s body might be there.

But Chief Inspector Pam Young, of the NSW Homicide Squad, said the psychic, who was joined by another person, had instead come across a torso (missing the head, arms and legs) wrapped in plastic on a creek bank.

"It is very sad to say that an adult female torso has been found where the witnesses said they thought there was a body," she said.
