ZURICH (AP) — A day after announcing his decision to resign, Sepp Blatter was back at work at FIFA headquarters on Wednesday as the worst corruption crisis in the governing body's 111-year history continued to unfold. Interpol added six men with ties to FIFA to its most wanted list, while South African officials denied they made a $10 million bribe to secure the 2010 World Cup. The international police force, based in Lyon, France, issued an alert for two former FIFA officials and four executives on charges including racketeering and corruption. The Swiss attorney general's office said Blatter was not under investigation, but said it has opened criminal proceedings against "persons unknown" for money-laundering.
