The Adjudicatory Chamber of FIFA's Ethics Committee has banned Adamu, who was given a three-year suspension in November 2010, for two years from "taking part in any kind of football-related activity at national and international level".

The Nigerian official, who was also once part of the Confederation of African Football (CAF) Executive Committee, was sanctioned as a result of "his involvement in the organisation of an event in 2010".

He was found to have breached the general rules of conduct, loyalty and conflicts of interest statutes of the FIFA ethics code.

"The adjudicatory chamber of the independent Ethics Committee, chaired by Hans-Joachim Eckert, has decided to ban the former football official Amos Adamu for two years from taking part in any kind of football-related activity at national and international level," a FIFA statement read.

The decision marks the conclusion of an investigation into Adamu which began in March 2015.

Adjudicatory proceedings were then initiated in December of last year after the Investigatory Chamber of the Ethics Committee recommended Adamu be banned for two years.

In November 2010, 62-year-old Adamu was banned from football for three years after a sting investigation by the Sunday Times.

The newspaper produced secret footage of him allegedly agreeing to sell his vote for the 2018 World Cup for a payment of $1.3 million (£1.1 million/€1.2 million) into his personal bank account. 

Adamu continued to deny wrongdoing after his ban, which expired in October 2013.

The Nigerian was previously director general of the National Sports Commission in his home country for 10 years. 

He was a member of FIFA's ruling Executive Committee, which has since has been rebranded as the FIFA Council, when Russia and Qatar respectively won the hosting rights for the 2018 and 2022 World Cup tournaments in December 2010.
