Seven people have been arrested as part of what the PSNI has described as Northern Ireland's largest money-laundering search operation.
Police say the operation focused on the international money laundering of criminal assets amounting to around €250 million.
Six men ranging in age from 33 to 67 and a 32-year-old woman were arrested during the two-day operation.
Four men have been released on police bail, while the remaining two men and a woman continue to be questioned by detectives.
A total of 15 properties were searched across Northern Ireland both today and yesterday - in Belfast, Banbridge, Newry, Omagh and Ballymena.
Detective Chief Inspector Ian Wilson says the investigation revealed that a significant volume of suspected criminal cash was being laundered out of the country through a number of shell companies and bank accounts held in Northern Ireland.
The investigation has identified over 50 companies and over 140 bank accounts suspected of being involved.
In total, almost £215 million pounds - or €250 million - has been deposited to thousands of bank accounts through foreign exchange companies since 2011.
