Jadue has since pled guilty in the United States to racketeering conspiracy and wire fraud conspiracy according to the U.S. Department of Justice, and has left his post as vice-president of South American soccer confederation, CONMEBOL.

"These assets, that at the request of Jadue himself were received by means of a foreign company incorporated in the British Virgin Islands, should have been declared in Chile," the nation's tax service said in a statement.
