AKIPRESS.COM - After a day of crisis, which saw 14 football officials and executives arrested at the request of the FBI, some in Zurich, and FIFA accused of "rampant, systematic and deep-rooted" corruption, the Swiss authorities said that Mr Blatter could be questioned.
The FIFA president was given the warning by the office of the Swiss attorney general. It is conducting its own inquiry into alleged vote-rigging over the Qatar World Cup bid.
The escalation of that inquiry came as the FBI claimed it had uncovered 24 years of "brazen corruption, undisclosed illegal payments, kickbacks and bribes" by FIFA officials. The American inquiry alleges that votes for the award of the 2010 World Cup - ultimately given to South Africa - were bought with bribes.
