Three years after the downfall of Ireland’s largest stockbroking firm, the Chartered Accountant Regulatory Board (Carb), the country’s watchdog for accountancy firms including Deloitte has failed to launch a formal investigation after a €5.3 million hole was discovered in a probe by the Central Bank, according to a report by The Irish Times.

It seems that the millions that went unaccounted for stretched back to 2007, however the firm’s auditor at the time, Deloitte approved and signed off on annual accounts prior to its collapse.
