On May 24, 1964, Peru took on Argentina in qualifying match for the 1964 Olympics in Lima. With Argentina holding onto a slim 1-0 lead, Bertolotti Andres of Peru scored the game-tying goal in the final minutes, a goal that would have been enough for Peru to qualify. However, the referee disallowed the score and in response, the fans started rioting. The police tried to settle the crowd down by firing tear gas into the stands, but when the people realized that there was no way out since the stadium had been inexplicably chained shut, the rioting turned deadly. Sadly, 318 people were killed.
