RIO DE JANEIRO — Several referees and judges have been removed from the Olympic boxing competition after officials reviewed their decisions, fueling suspicion of dubious results in some matches at the Rio Games.

A spokesman for the federation that governs the boxing tournament said Wednesday that the names of the referees and judges who were dismissed, and the matches that were tainted, would not be released because he did not want to “besmirch their families.”

The international federation, known as AIBA, said in a statement that the committee that reviews officiating had assessed all 239 bouts at the Rio Games through Tuesday and had “determined that less than a handful of the decisions were not at the level expected.”
