FIFA have banned former Secretary General Jerome Valcke from all soccer-related activities for 12 years, after its investigation found acts of potential misconduct, its ethics committee said on Friday.

Valcke was fired by world football's governing body in January amid allegations of corruption in relation to the sale of World Cup tickets.

"During the course of the investigations, several other acts of potential misconduct arose, in particular abuse of the FIFA travel expenses policies and regulations, cases involving related-parties issues and the sale of TV and other media rights, and the destruction of evidence" a statement said today. 

"Amongst other things, the adjudicatory chamber found that a sports marketing firm had gained an undue advantage from the selling of FIFA World Cup™ tickets. In this respect, not only did Mr Valcke do nothing to stop these activities, he even encouraged the persons responsible to do so" it went on to say.

"Furthermore, Mr Valcke repeatedly encouraged them to breach an agreement concluded between FIFA and the sports marketing firm."
