Police investigating a suspected money laundering operation carried out a series of raids in Derry today.
The PSNI said the investigation is not connected with the £26.5 million Northern Bank robbery.
Computers, filing cabinets full of documents, fax machines, photocopiers and other items were seized from offices at Waterloo Street and Harvey Street.
A house at Victoria Road in the Waterside was also searched. No arrests were made.
Despite ruling out a Northern Bank connection it is understood links to republican and loyalists paramilitaries and the alleged money laundering has not been ruled out by detectives.
