The International Boxing Association (AIBA) has suspended African Boxing Federation (AFBC) President Kelani Bayor for three years for "serious and unacceptable violations of the disciplinary code".
Bayor, a member of AIBA's Executive Committee and a vice president, has been banned following an alleged incident during June's African Boxing Championships in Brazzaville.
It has also led to hosts the Congolese Boxing Federation (FECOBOXE) being excluded from organising any AIBA event for two years.
The sanctions are said to follow hostilities towards AIBA staff by fans at the event, which the governing body believe were made worse by Bayor.
FECOBOXE have been slammed for alleged poor security arrangements and a bad response to the situation.
Both punishments have been issued by the AIBA Disciplinary Commission and follow reports from officials who were at the event, the governing body said.
AIBA said they had taken a "strong stance after critical interference".
"The Disciplinary Commission found that a hostile and threatening reaction to AIBA officials by spectators after the result of a bout on the last day of the competition was exacerbated by comments from Mr Bayor, who committed serious and unacceptable violations of the AIBA Disciplinary Code," an AIBA statement said today.
"The intimidation felt by AIBA officials as a result of insufficient security planning from FECOBOXE, their inadequate response to the situation and Mr Bayor's own actions, was fully outlined in the tournament supervisor's written report.
"The Commission's decision was also based on written testimony from the majority of those officials present.
"The Commission's decision is final and is not subject to appeal."
Today's news comes amid a bitter power struggle at AIBA, where President CK Wu is opposed by a breakaway Interim Management Committee (IMC).
This was formed after 13 of the 15 Executive Committee members opposed Wu at a meeting in Moscow.
An Extraordinary General Assembly is likely to be held in October in Lausanne at which national governing bodies - as statutes dictate - will decide on whether Wu retains his position.
The IMC claim this crucial meeting, however, will take place in Dubai on November 12 and would like a pre-meeting to be held in the same city on September 23.
The suspension of Africa's foremost boxing official also comes after AIBA dedicated 2017 to the continent.
Known as the "Year of Africa", a continent-wide programme has been launched which aims to bring education, empowerment and a lasting legacy for boxing at the start of the Tokyo 2020 Olympic cycle.
In March, Bayor spoke glowingly about the scheme.
He is no stranger to controversy, however, after denying in November 2015 a claim that he "would not permit" a Togolese boxer to undergo a routine anti-doping test at the All-Africa Games, which also took place in Brazzaville.
The allegation was included in a World Anti-Doping Agency independent observer report but Bayor protested his innocence to insidethegames.
The Championships in Brazzaville, the capital of the Republic of Congo, were beset with difficulties before the action had even begun.
Boxing had been due to start on May 27 but a reschedule was announced less than a week before to "meet the high standards demanded".
No exact reason was given with competition instead starting on June 17.
insidethegames has attempted to contact Bayor for comment.
