Police are spending a third day digging up a garden following reports a body is buried there.
Crime scene investigators spent a second night at the semi-detached house in Knowsley Crescent, Thornton, where they are excavating the back garden.
Two tents have been put up behind the house and police have now removed the top layer of soil.
However, the team, led by Detective Inspector Paddy O’Neill, from the Force Major Investigation Team, has made clear nothing significant has yet been found.
A spokesman for Lancashire Police today said work at the site was continuing today but said there was nothing new to report.
