Counterfeit designer sportswear and leisurewear and around £30,000 in cash were seized in searches in Craigavon and Belfast on Monday.
The raids were carried out by detectives from Reactive and Organised Crime Branch as part of an investigation into counterfeit goods.
Four residential properties in the Craigavon area were searched as well as commercial premises in Belfast.
Temporary Detective Superintendent Gary Reid said: “Officers seized three vehicles at Craigavon addresses and we are examining various items which we suspect to be counterfeit designer sportswear and leisurewear.
“Cheap counterfeit goods appear to be a bargain which isn’t hurting anyone but there is no such thing as a victimless crime. Revenues to the legitimate economy are lost and jobs put at risk.
“There is also a wealth of evidence that money made from counterfeit goods is used to fund other forms of crime including drugs.”
