Ian Bailey has been arrested and bailed in connection with the death of French filmmaker Sophie Toscan du Plantier.
He was arrested after a High Court judge endorsed a European Arrest Warrant issued by the French authorities, who want to try him for voluntary homicide.
Mr Bailey (60), of The Prairie, Liscaha, Schull, Co Cork, was subsequently remanded on bail following a short hearing.
Detective Sergeant Jim Kirwan told the court that he arrested Mr Bailey at the Criminal Courts of Justice at 10.21am, about 20 minutes after the warrant was endorsed.
Det Sgt Kirwan handed him a copy of the arrest warrant and, when asked if he wished to say anything, Mr Bailey responded: "The warrant, as read to me, is severely factually flawed."
His legal team has previously told the court that they intend to oppose the application to have him sent to France.
Mr Justice Tony Hunt said bail is not an issue in this case. He set bail at €15,000 on Mr Bailey's own bond with no lodgment. He must remain at his current address and hand over his expired passport to gardaí.
He must not leave the jurisdiction without permission from the court and must attend the High Court when required.
The judge set a date for next Friday, April 7, to hear submissions relating to the application made by the French authorities. He told Mr Bailey that he is not obliged to attend in person on that date.
He told Mr Bailey's legal representatives it would be best if they have their submissions ready at that time, adding: "The quicker you get them in, the quicker we can work towards dealing with the matter."
French authorities have already served Mr Bailey with an indictment and want him to face trial in France for the alleged voluntary homicide of Ms Toscan du Plantier, who was found beaten to death outside her holiday home in Schull in December 1996.
Mr Bailey has denied all links to the death of Ms Toscan du Plantier and alleges a Garda conspiracy to frame him.
This is the second time the French authorities have tried to bring Mr Bailey to France following a rejection by the Supreme Court in 2012.
A jury who dismissed Ian Bailey’s civil claim alleging gardai conspired to frame him for the murder of Sophie Toscan du Plantier got no opportunity to consider the conspiracy claims in full, Mr Bailey’s lawyers have told the Court of Appeal.
