A full DNA profile has been created of an unidentified woman whose body was found in North Yorkshire in 1981.

As part of a cold case review, the body was exhumed at Malton cemetery in January in order to recover DNA material that might help identify her.

The body was found on a remote country road in Sutton Bank following a tip-off from an anonymous caller.

Police have revealed the caller said he could not reveal his identity "in the interests of national security".

Det Supt Lewis Raw, from North Yorkshire Police, said the DNA profile would now be checked against other people who had contacted police believing that the woman may be a relative or friend.

"We are very pleased with the outcome of the tests.

"Due to the length of time that the body had been buried at the cemetery in Malton, there was a possibility that a full profile might not be obtained."

Mr Raw added: "The DNA profile will now be checked against the people who have come forward to identify any familial link with the deceased.

"However, before any samples are taken from the people who have come forward, research will be conducted around physical similarities between the families and the deceased, including dental records and other physical characteristics."
