Mr Sam Field-Corbett (60), a businessman who was named in the Ansbacher Report as having possibly committed a criminal offence, has moved to the Isle of Man.
Mr Field-Corbett was a close associate of the late Mr Des Traynor and following Mr Traynor's death in 1994 the computer used to monitor the Ansbacher accounts was moved to Mr Field-Corbett's offices on Winetavern Street.
Mr Field-Corbett is known to have been deeply upset by the inquiries into his affairs and damage to his reputation that has occurred since the discovery of the Ansbacher deposits in 1997.
The reason for his move to the Isle of Man is not known and he could not be contacted yesterday.
The latest returns for a number of companies he is involved in indicate he moved during the past year.
The Director of Corporate Enforcement, Mr Paul Appleby, is currently considering the Ansbacher Report with a view to deciding what actions should be taken arising out of it.
Gardaí from his office have served papers on Mr Padraig Collery, another former associate of Mr Traynor's, who was heavily criticised in the report.
Mr Collery moved the Ansbacher files to Mr Field-Corbett's office following Mr Traynor's death.
The documentation served on Mr Collery was in relation to a High Court hearing where the director is seeking access to the inspectors' papers in relation to a number of individuals, in order to develop a more complete understanding of how the inspectors reached their conclusions.
Following the death of Mr Traynor, Mr Collery took on an increased role in the running of the Ansbacher deposits, operating from Mr Field-Corbett's offices.
Mr Field-Corbett began his career with Haughey Boland where he worked as an assistant to Mr Traynor and specialised in secretarial services.
He subsequently set up his company, Management and Investment Services, at the suggestion of Mr Traynor.
Many of the people and companies mentioned in the Ansbacher Report made use of Mr Field-Corbett's services, including the property developer, Mr John Byrne, one of Mr Traynor's most significant clients.
Mr Field-Corbett also did company secretarial work for Mr Charles Haughey.
Mr Field-Corbett had a trust managed by Guinness Mahon Cayman Trust, which he told the Ansbacher Inspectors had been established on his behalf by Mr Traynor in the mid-1980s.
