More than 90 per cent of non-resident deposit accounts held in an unnamed industrial bank were bogus, a former employee of the bank has told RTE. Interviewed on last night's Money Box programme on Network Two, the man said that throughout the 1970s, 80s and 90s, the bank used bogus offshore accounts as well as multiple accounts in fictitious names to help depositors evade tax. Directors knew of the policy but told him they would not stand over it in the event of a Revenue investigation. Over a 20-year period the Revenue never investigated.
