Human remains found at a building site in a south Northamptonshire village have been sent to experts for carbon dating.
Two sets of human remains were found at a site in Middleton Cheney on Friday and police have today revealed they have now been taken away for further examination.
The tests are expected to take several weeks.
A police spokesman said early enquiries with archaeologists suggest that there is nothing suspicious.
No other artefacts have been found at the site to date.
Detective Inspector Louise Fleckney said: “We have been working with archaeologists and while we cannot know for sure until carbon dating has been carried out the early indication is that this is an ancient burial site rather than a crime scene.
“Further enquiries may continue at the site but we would like to reassure the public that we are treating the site as an ancient burial site rather than a crime scene.”
