Brazilian fans at Rio's Olympic Stadium ignored requests to behave themselves as French pole vaulter Renaud Lavillenie was greeted with a chorus of boos as he received his silver medal today.
Lavillenie reacted furiously to the partisan treatment he received during yesterday's tussle with local hero Thiago Da Silva, but it continued as he took to the podium in tears today.
"That is just wrong," former British runner Paula Radcliffe said on Twitter. "Ashamed of the track and field crowd tonight. Cheer your own as loud as you like but never disrespect the others."
The 22-year-old Brazilian beat the defending champion in a thrilling contest, but it was marred by large sections of the crowd booing Lavillenie's attempts.
The hostile atmosphere clearly unsettled the Frenchman, who gave fans the thumbs-down sign between attempts and in his first interview after the event likened his treatment to the reception America's black sprinter Jesse Owens received at the 1936 Olympics in Germany.
