The jury in the trial of three former Anglo officials convicted of trying to hide accounts connected to the bank's former chairman Sean FitzPatrick reached a verdict just after 12.30pm.
However, delivery of the verdict was delayed after prosecutor Dominic McGinn told the court the DPP's office had received a phone call in the previous few minutes suggesting the jury was not wholly independent.
Mr McGinn asked the judge not to receive the verdict until the phone call could be investigated.
After lunch the prosecution handed in a statement from the person who had taken the call.
Mr McGinn said there were a number of details that seemed to be incorrect and that cast doubt on the veracity of the call.
He said there were some indications of a connection between two people of the same name and two entirely unconnected people.
He said the DPP's instructions were to take the verdict.
Lawyers for Aoife Maguire and Bernard Daly had no objection to this. But lawyers for Tiernan O'Mahoney said the call was extraordinarily accurate in relation to a number of matters.
Senior Counsel Brendan Grehan said there was a very real concern that the jury process had been tainted in some way and he asked for the jury to be discharged.
This application was refused by the Judge Pat McCartan, who then called in the jury.
He told the foreman he did not want to cause him undue embarrassment but he asked him if his wife was very friendly with Maguire, as the anonymous caller had suggested.
The foreman said this was not the case and the jury went on to deliver its verdicts.
O'Mahoney, Anglo's former chief operating officer, Daly, Anglo's former company secretary, and Maguire, a former assistant manager at the bank, were found guilty of all charges.
Judge McCartan said the verdicts showed what the caller had said was a falsehood.
