Probe involves thousands of files
Q GARDA fraud bureau investigators and investigators from the Office of the Director of Corporate Enforcement (ODCE) have been studying documentation, computer files and tapes since two joint raids on the headquarters of Anglo Irish Bank four years ago.
During the raids they seized hundreds of thousands of documents and files.
The two searches were carried out within seven months of each other in 2009 after the ODCE had applied to Dublin district court for warrants.
Following negotiations the bank and the ODCE agreed that some files should remain confidential.
But a spokesman for the investigators said that while some material had been adjudged to be within the "legal professional privilege, off limits rule", the number of files involved was not major and would not hamper their inquiries.
The seized material was later used in the interviewing of vital witnesses and formed part of files that were subsequently sent to the Director of Public Prosecutions.
Gardai are currently awaiting a decision from the DPP on some of the files to determine whether they should result in prosecutions.
