ZURICH — FIFA President Sepp Blatter was interrogated by Swiss federal police on Friday and faces criminal charges over alleged financial corruption. Switzerland’s attorney general’s office said Friday it opened criminal proceedings against Blatter for possible criminal mismanagement and misappropriation of FIFA money. The Swiss federal prosecutor’s office also said Blatter’s office was searched and data was seized. FIFA vice president Michel Platini was also questioned as a witness over a “disloyal payment” of 2 million Swiss francs he received from Blatter in February 2011, Swiss authorities say.
