World football's embattled governing body has been engulfed in more scandal with another 16 officials charged over graft allegations.
Two senior FIFA bosses heading powerful American associations are among those accused of taking part in a multi-million dollar broadcasting rights bribery scam.
As world football officials gathered in Zurich to try to work their way through the gloom that's descended on FIFA over corruption allegations, Swiss police pounced in pre-dawn raids at a nearby hotel.
Arrested were football bosses Alfredo Hawit and Juan Angel Napout - the Paraguayan head of the South American football federation.

Spokesman for the Swiss Federal Office of Justice, Folco Galli, confirmed the arrests were made at the request of United States counterparts.
"FIFA officials are suspected of accepting bribes of millions of dollars in return for selling marketing rights in connection with football tournaments in Latin America, as well as World Cup qualifying matches."
In Washington DC, Attorney-General Loretta Lynch told reporters the United States would seek the pair's extradition from Switzerland.
"The betrayal of trust set forth here is truly outrageous. The scale of corruption alleged herein is unconscionable. And the message from this announcement should be clear to every culpable individual who remains in the shadows, hoping to evade our investigation: You will not wait us out. You will not escape our focus."
Honduran Alfredo Hawit was only recently appointed acting president of the 41-country strong North and Central American association.
His arrest stunned Honduras Football Federation secretary, Jose Ernesto Mejia.
(Translated)"The whole of the executive committee and the federation is, quite frankly, surprised. We trust this situation can be favourably solved by President Hawit. We trust in his good work. He's a person who has acted with honesty."
All up, 16 officials have been charged over broadcasting and marketing rights graft allegations in the latest round of arrests -- taking the number to 27 since May.
Acting FIFA President Issa Hayatou says the arrests are evidence of a need for organisational change.
"The investigation is going on, and FIFA is ready to participate fully. In the light of what is going on, all this we can say is that FIFA will not make any other comment."
The latest scandal overshadows the FIFA executive commitee's approval of a reform package put forward by chairman Francois Carrard.
"We all know, you all know, that FIFA is going through a major crisis. As we also all know a crisis is a unique opportunity for a change, fore renewal, and for commencing a new period of its very rich history."
But some critics say internal change is not enough and football's scandal-plagued governing body needs a complete reboot.
