There was an unusual guest joining the raucous Brazilian crowd at the men’s volleyball semifinals.
A large bat started flying around the arena as Brazil played Russia for a spot in the final.
The bat went across the court above the players then started flying low near the fans on the stands, amusing the crowd and momentarily taking its attention away from the match.
Some fans had to duck as the animal went around a few times before eventually finding its way out through one of the exits.
The match was not interrupted, and Brazil went on to win in three sets to reach its fourth straight Olympic final.
