The FIFA corruption scandal took another twist Monday after the organisation revealed its deputy secretary general had been sacked.

Markus Kattner was handed his dismissal papers after world football's governing body, according to a statement, "uncovered breaches of his fiduciary responsibilities in connection with his employment contract".

FIFA said it would not make any further comment, but would "continue its cooperation with the relevant authorities."

An internal investigation revealed he got irregular bonus payments worth millions of dollars. The extra payments were signed off by then-President Sepp Blatter and then-secretary general Jerome Valcke, Kattner's immediate boss in that period.

The 45-year-old was not available to comment after the decision but FIFA were keen to make it clear he had not been charged with any crime. But, Kattner's downfall topples another member of ex-president Sepp Blatter's inner circle at football's world body.
