A man arrested by police in connection with the murder of Bangor woman Lisa Dorrian has been released.
Lisa left her handbag and personal belongings behind at a party
The 25-year-old has not been seen since leaving a party at a caravan park in Ballyhalbert on 28 February. Her body is yet to be found.
Earlier on Tuesday, police officers searched a yard behind premises in Ballywalter, County Down, at the junction with the Greyabbey Road.
Two other men questioned about the murder were released on Friday.
When she disappeared, Lisa, a shop assistant, left her handbag and personal belongings behind her and has not made contact with friends or family since.
Detectives investigating the murder returned to the caravan park on Saturday to talk to caravan owners and local residents.
A caravan from the site has been removed for examination and a number of premises in Ballyhalbert and elsewhere in County Down were searched last week.
Extensive air and land searches have taken place since her disappearance. Underwater search teams were also used.
