New search in missing woman inquiry
Detectives investigating the murder of a Co Down hairdresser seven years ago have undertaken a fresh search.
The body of 25-year-old Lisa Dorrian has never been found.
However it is understood the new preliminary search on the site in the Comber area is not for human remains.
Ms Dorrian was last seen at a late night party at a caravan park in Ballyhalbert, Co Down in February 2005.
Police have treated her disappearance as murder.
No one has ever been charged with the crime despite a number of arrests.
