Police investigating the pre-Christmas robbery at Northern Bank headquarters in Belfast are continuing to search two houses and a scrapyard in Co Tyrone.
The on-going searches were mounted yesterday near Beragh as part of the investigation into the £26.5m (€38m) heist, which has been blamed on the Provisional IRA.
An area of land has been dug up during the operation, while the PSNI is also using radar equipment to assist in the search and divers have been brought in to check out a duck pond.
It is not known if anything has been found during the searches, which have been condemned by Sinn Féin.
Local assemblyman Barry McElduff said the PSNI was causing huge upset to the families involved.
