In a repeat of raids held earlier this year, Swiss authorities held several high ranking FIFA officials at the behest of the US Justice Department as part of the ongoing investigation into FIFA corruption. The most high profile names held for extradition were Honduras' Alfredo Hawit, present Concacaf President and Juan Ángel Napout of Paraguay, the present head of Conmebol. The two predecessors of these two positions have also been held previously for similar offences.
Trinidad and Tobago's Jack Warner is one of the names currently fighting extradition to the USA and just yesterday got his case adjourned until February 2016.
The US Attorney General, Loretta Lynch, is expected to hold a similar press conference to the one made when the initials raids began, where she will list the new evidence against the 12 officials held.
Notably, high profile European names who are currently under internal investigation by FIFA such as Sepp Blatter, Jerome Valcke, Michel Platini and Franz Beckenbauer have not been named in this criminal part of the investigation.
