The move was carried out following requests by the United States Department of Justice (DOJ), who have so far indicted 41 officials and entities in their probe into alleged criminal activity in world football's governing body, three of which have served as President of CONMEBOL.

According to a statement from the prosecution office, the raid sought documents detailing "business concessions and broadcasting rights for sporting events".

Paraguayan Juan Angel Napout, a FIFA vice-president and head of CONMEBOL before his arrest ahead of the Executive Committee meeting in December, as well as past heads of the organisation, Nicolás Leoz of Paraguay and Uruguayan Eugenio Figueredo, have all been indicted.

CONMEBOL lawyer Cristóbal Cáceres claimed the raid largely centered on Leoz, who was arrested ahead of FIFA’s Congress in Zurich in May, and his role in accepting and soliciting bribes in exchange for media and marketing rights to tournaments and matches in the region.

The 87-year-old, who led CONMEBOL from 1986 to 2013, has been under house arrest since May and is facing extradition to the United States.

“We are providing the documents that are being asked for,” Cáceres said.

He added “some of the documents pertaining to doctor Leoz are not here”.

Alfredo Montanaro, another lawyer for the body, which remains at the heart of the scandal engulfing world football, felt the raid on the CONMEBOL headquarters was “irresponsible” and “strange”, insisting they had been “cooperating with the judicial authorities of the United States, Uruguay and Paraguay.”

Napout has since resigned from his role as CONMEBOL chief and has denied bribery charges in a Federal Court in Brooklyn, New York City, while Figueredo, also a former vice-president, was accused of receiving £33,000 ($49,000/€45,000) in bribes per month during his hearing in his native Uruguay.

He is facing the prospect of 15 years in prison and spent Christmas Day in jail.

Rafael Callejas, the former President of Honduras, has also denied corruption allegations in the Federal Court after voluntarily travelling to the US to face the charges.

Suspended Guatemala Football Federation secretary general and judge Héctor Trujillo, among the 16 indicted in December, pleaded not guilty to charges in the US and has been placed under house arrest.

He has been ordered to wear an electronic monitor as part of the conditions of his bail.

Trujillo’s bond has been set at $4 million (£2.7 million/€3.7 million).
