Ian Bailey has described as 'sinister' the fact that gardai passed on to the French authorities evidence that had been repeatedly rejected in Ireland.
The former journalist has spent a third day giving evidence in his wrongful arrest action in which he claims gardai concocted evidence against him over the 1996 murder of French film producer Sophie Toscan du Plantier.
'Sinister' and 'frightening' were the words Ian Bailey used in court to describe the gardai's decision to hand over his file to the French authorities.
He claims France was fed falsehoods by the gardai and in 2010 he was detained in Mountjoy prison on a European Arrest Warrant.
He said he was held in a cell which you wouldn't put a dog in – he told the court there was an open sewer and he couldn't eat a sandwich because of the stench.
However, he said the cruellest thing about the warrant was that it stopped him travelling to see his mother before she died and as a result he's never been able to properly grieve for her.
Ian Bailey will be cross examined when he returns to court next Tuesday.
Lawyers today began their cross examination of Ian Bailey on day three of his High Court action for damages for alleged wrongful arrest.
The former journalist, with an address in Schull, Co Cork, is suing the state and the garda authorities claiming gardai concocted evidence against him in connection with the 1996 murder of French film producer Sophie Toscan du Plantier.
The state parties deny all the allegations.
Mr Bailey (57) has spent three days in the witness box so far.
Yesterday, Mr Bailey claimed the first time he was brought to Bandon garda station, the driver of the police van, Garda Liam Hogan told him, ''Even if we don't pin this on you, you are finished in Ireland. You'll be found in a ditch with a bullet in the back of the head.''
Mr Bailey told the jury he interpreted this as a death threat.
He claimed prior to his arrest Garda Superintendent Dermot Dwyer told him he was going to place him on Kealfadda Bridge, which was close to the murder scene, early on the morning of the killing.
The jury also heard he was accused of trying to intimidate a potential witness Marie Farrell, who allegedly approached him in 1997 over concerns that an innocent man was being framed.
He denies ever making a cutthroat gesture at the shopkeeper who is due to give evidence in the coming weeks.
