A professional bodybuilder has forcefully slapped a respected judge across the face after losing a competition in Greece. Giannis Magos thought the title was in the bag at the 2016 IFBB Diamond Cup after he was declared the winner of the 100kg division. Despite his high points tally, the athlete was not declared the overall winner of the competition. Mobile phone video taken backstage at the weekend showed Magos approach long-time respected judge Armando Marquez. After a few heated words the massive man slapped the MC across the face – knocking him to the ground.
