Further warrants in commercial premises have been executed and an RGP spokesman did not rule out further arrests.
The two suspects, a husband and wife couple who are believed to have strong links with organised crime groups in Spain, are currently on police bail.
An RGP spokesman said: “Cross border cooperation between law enforcement organisations to tackle transnational organised crime, drug trafficking and money laundering activities is stronger than ever. These groups have no boundaries or borders and we will pursue them tirelessly and also those who facilitate money laundering of the proceeds of crime.
Our efforts will continue unabated.”
