Roger Giese, 50, fled the US in 2007 and became one of the FBI's most wanted fugitives until he was reportedly arrested at his home in Broughton last year.
An investigation by the Mirror found Roger Giese, 50, fled the US in 2007 and became one of the FBI's most wanted fugitives.
It's claimed he has been in Britain since at least 2009, using the name Jonathan Roberts, running a Christian charity called Atlas Christian Outreach Ministries and working as digital media expert.
Under his real identity of Roger Alan Giese he is wanted on 19 charges of grooming and sexually assaulting a boy in California in the late 1990s. It's alleged he met the teenager while coaching a choir then befriended his family at his church.
Mr Giese says if he returns to the US he could be given an open-ended prison sentence known as "civil commitment". The punishment sees prisoners detained until it is deemed they have had enough treatment to prevent them reoffending. His lawyers say this could breach Mr Giese's human rights.
A district judge reportedly refused the extradition request at Westminster magistrates' court but the US government has appealed and a judgment is pending.
A spokesman for the Home Office said: "Roger Alan Giese is the subject of an extradition request from the United States. The Crown Prosecution Service has appealed against the decision of the district judge to discharge him, and we await the judgment of the High Court."
Hampshire police said it could not comment on individual cases but said offenders considered to pose a risk to the public were closely monitored.
