His son fled to Fermanagh, evading a three-month jail sentence in the Republic for contempt of court proceedings and a warrant issued for his arrest on Friday, Jul 20 last.
Speaking to the Joe Finnegan Show on Shannonside Radio, Mr Quinn, the brother of bankrupt businessman Seán Quinn, told listeners: “Well, first of all my son is not a fugitive, he is not on the run, he is living at home in Fermanagh.
“I am making an allegation of all law and order in the South and I have lost all faith in the South’s legal system.
“Why should he go back to the South to face injustice? But I know Peter did try to purge his contempt at least twice with Anglo but they would not accept it and refused to co-operate with him.
“But I will back him either way on what he wants to do.
“Peter believes he was set up after making every attempt to purge his contempt of court,” Mr Quinn said.
He also said he tried to get Anglo and its chairman Alan Dukes to negotiate, twice, but he refused.
“Well, I spent six years as a mediator on the Parades Commission in the North and also in the Garvaghy Rd, so I know about being a mediator, but when the two parties do not talk what can you do. Anglo would not talk to us.”
As to the question of a rift in the family, Peter Quinn Sr strongly denies this.
“The Quinns will stick together through thick and thin and that’s for sure.
“There is an element of double-cross in this and there was a double-cross in the Ukraine and Anglo know that, but people should know Seán Quinn never borrowed anything from the Irish taxpayer and anything they done was 100% legal in the country it was done in, including the Ukraine,” he said.
