More than 10 bouts in the 2016 Rio Olympics boxing competition were manipulated for money and other perceived benefits, an independent investigation has revealed, prompting the International Boxing Association (AIBA) to promise a tough selection process for referees and judges at the upcoming men’s world championship.

The first phase report of the McLaren Global Sport Solutions’ independent investigation into boxing has been handed to AIBA and revealed that “a system for the manipulation of bouts by officials existed at Rio.” In all, 14 bouts came under the scanner, including two finals.
