Two men remain in custody in Northern Ireland for questioning over the disappearance of Lisa Dorrian (25), who disappeared from a seaside caravan park on February 28 th.
The men can be held for up to 48 hours.
Forensic experts examined items from the a house which was searched today on the Ards Peninsula in Northern Ireland.
Officers spent up to 36 hours trawling though the house in an attempt to find clues that could help end the agony for the missing shop assistant's family. A caravan was also removed from a site in the village which looks out over the Irish Sea.
The village has a population of less than 1,000 people. Ms Dorrian, who lived 10 miles away in Bangor, was last seen leaving a party at the park where she had been spending more and more time early on February 28th.
Air and land searches were carried out along the coast, with police divers also brought in to strengthen the effort.
