The PSNI have seized thousands of counterfeit DVDs and a quantity of counterfeit CD's were seized during the planned search of a private house at Clontigora Hill outside Newry.
The operation was carried out by the Police Service Organised Crime Unit. About 5,000 DVDs, the CDs and 15 printers and scanners were found during the raid.
DVD titles ranged from Harry Potter to the Dukes of Hazard. A police spokeswoman said the search was part of an ongoing PSNI drive against organised crime in the border areas of Northern Ireland.
One man was arrested and was later being questioned by detectives.
