Over 20,000 counterfeit devices, most of them Apple’s, including iPhones, AirPods, chargers, unspecified smartwatches and mobile phones were seized at two premises in Belfast and Portadown, Northern Ireland, the BBC reports.

The estimated total value of the products is around $750,000. In addition, cash was also seized, police said.

The Northern Ireland operation was carried out by the PSNI’s Organised Crime Unit.

Police warn that such counterfeit goods often fund organized crime. In most cases they are produced in factories where “a vulnerable group of people work tirelessly in appalling conditions and are paid a pittance”, said Detective Sergeant Mason of the PSNI (Police Service of Northern Ireland).

No specific charges have yet been laid in the case. According to media reports, a 24-year-old man was arrested in Portadown on suspicion of immigration offenses.

Details are yet to be clarified.
