Fifa said "the sanction is effective from 28 February 2017".

Adamu, who was previously banned for three years from October 2010, has been punished for violating three articles of Fifa's Code of Ethics.

The 64-year-old has been found guilty of violating general rules of conduct, loyalty and conflict of interest.

Fifa said Adamu's misconduct relates to "his involvement in the organisation of an event in 2010, while being a member of the (then) Fifa Executive Committee".
