A video and pictures have been released by police as the search for Keith Bennett continues on Saddleworth Moor.
The 12-year-old is the only victim of Ian Brady and Myra Hindley who has never been found.
In footage released by Greater Manchester Police, two tents with forensic officers are shown on the site following the discovery of a skull.
The Daily Mail reported that the skull is believed to be that of a child aged around 12.
Police are warning people against people attending the site.
The investigation comes after a tip off yesterday afternoon, Thursdau, from an author researching the murder of Keith Bennett.
The 12-year-old was last seen on June 16, 1964, when he left his family home to stay with his grandmother.
Brady and Hindley murdered five children between July 1963 and October 1965 and extensive searches of the Moors led to the bodies of Pauline Reade, 16, John Kilbride, 12 and Lesley Ann Downey, 10, being found.
However, Keith Bennett's was not found and searches for him stalled following the death of Brady in 2017.
