Allied Irish Banks (AIB) has called in the fraud squad to investigate suspicious transactions on deposit accounts it bought from disgraced Anglo Irish Bank.
It is understood a complaint from a customer who believes money was missing from an account sparked the probe.
The amount of money involved is not known but it is understood to be a fraction of the €8bn deposit book purchased from Anglo in February.
An AIB spokesman confirmed the investigation but would not divulge any further details on the probe while both the Garda fraud division and the Central Bank have been alerted.
“As a result of a recent customer inquiry, AIB began an investigation into whether any fraud occurred in a small number of transactions concerning certain, discrete funds, in the deposit book that was acquired from Anglo Irish Bank.
“In the event that fraudulent activity has occurred, AIB confirms any such transactions will be for the account of the bank and that customers will suffer no financial loss,” AIB said in a statement.
