A man described by the FBI as the "largest facilitator of child porn on the planet" could soon be extradited from Ireland to the US.
Eric Eoin Marques, 28, is wanted over four charges linked to images described as being extremely violent, graphic and depicting the rape and torture of pre-pubescent children.
Marques, who has Irish and US citizenship, has appeared in Dublin's High Court where extradition proceedings are under way.
Patrick McGrath, senior council for the attorney general of Ireland, said Marques was wanted in connection with the advertising, distribution and conspiracy to advertise and distribute the child abuse images.
The charges date from July 24, 2008 to July 29, 2013, two days before his arrest.
He is accused of being the sole administrator of a server where multiple websites were held and where it is alleged the abuse images were shared
If convicted, Marques faces up to 30 years in a US jail.
An FBI special agent previously told the court that the suspect is accused of being "the largest facilitator of child porn on the planet".
The US has sent a formal request for extradition and a certificate has been granted by Ireland's Justice Minister Alan Shatter.
Marques has denied being the administrator of an anonymous hosting server.
The judge adjourned the case until September 11 and remanded him in custody.
