"FIFA became aware of the actions taken today by the US Department of Justice. FIFA will continue to cooperate fully with the US investigation as permitted by Swiss law, as well as with the investigation being led by the Swiss Office of the Attorney General," a statement said.

Authorities have said for months to expect a second wave of corruption charges in soccer following US charges in May against 14 officials and sports marketing executives with paying and taking bribes.

US Department of Justice officials were expected to appear at a news conference in Washington as soon as Thursday to discuss the case, people familiar with the plans said.

The FOJ said it would issue another statement with the names of those who have been arrested later on Thursday.
