No disciplinary action was taken against a senior staff member who opened a non-resident account in ACC's Tallaght branch in 1993, the bank's former chief executive told the DIRT inquiry.
Mr John McCloskey, who was asked on Tuesday by the committee chairman, Mr Jim Mitchell, to get details of the case, said the Tallaght branch manager was no longer employed by ACC and the senior staff member with the bogus account had not been disciplined for lack of evidence.
Mr Mitchell said it surprised and disappointed him that the committee could not get more information on this and he would come back to it.
The committee was also told that there were two other cases of staff members having bogus non-resident accounts, one in Tuam, Co Galway, where the person had come back from Britain and deposited sterling in the branch.
Mr McCloskey said the branch manager did not know about it and, when the matter was discovered, about £162 was paid to Revenue.
The third case occurred in Tullamore, Co Offaly, and the staff member was dismissed, but Mr McCloskey said he did not have details of the settlement made.
Mr Sean Ardagh asked him to provide details of the Tullamore case as well as the Tallaght one.
