Sean Quinn has today accused an IBRC executive of being vindictive and pursuing him to the death.
The bankrupt businessman is in the witness box in the High Court for a third day as part of contempt proceedings that could result in his imprisonment.
He denies breaching a court order from last summer, directing the Quinns not to disperse €500m worth of assets.
Quinn admits that he gave the order to family members or, as he called it, his "war cabinet" to push valuable international assets beyond the reach of the former Anglo Irish Bank (now known as IBRC).
He said he made the decision after Anglo "did the dirty" and took over the Quinn group on April 14 last year.
However, he is being cross examined to test his continued denials that he had any knowledge of the plan's details or the international corporate structure that held the assets in countries like Russia and Ukraine.
At one point, Mr Quinn let fly against an IBRC executive Richard Woodhouse accusing him of pursuing him to the death and vindictively overturning his UK bankruptcy.
The accusations were immediately branded untrue by IBRC's lawyers.
