French pole vaulter Renaud Lavillenie

Devastated Olympic athlete cries on podium after being booed by hostile Brazilian crowd

International Olympic Committee president Thomas Bach described the crowd's behaviour as "shocking" and "unacceptable at the Olympics".

Lavillenie had been booed by the crowd during Monday's competition, as he battled Brazilian Thiago Braz da Silva for gold, giving a thumbs-down gesture to the cameras as he prepared for an attempt.
