Usain Bolt has secured an unprecedented Olympic "triple-triple" by winning his third gold medal at Rio and ninth overall, anchoring Jamaica's 4x100m relay team to a historic victory on Saturday.
Bolt flew down the home straight to claim the gold for Jamaica, meaning that he finishes with the 100m, 200m and 4x100m sweep in three consecutive Olympics.
The Jamaican team of Asafa Powell, Nickel Ashmeade and Yohan Blake set up the last leg of the relay for Bolt who stormed home, overtaking Japan that finished second.
The USA, which had been tipped to push Jamaica, finished in third place but was disqualified, elevating Canada to the bronze medal position.
Bolt and the Jamaican team celebrated in the stadium, jogging over to the various pockets of Jamaican supporters, with the crowd chanting Bolt's name.
Jamaica finished in a time of 32.27 seconds, followed by Japan on 37.60 and Canada 37.64. China was fourth.
Bolt said it was now official that he was "the greatest".
"My team came through for me tonight. As long as we got the baton round, it was never in doubt," he said post race.
"I'm going to stay up late and have fun. I never knew this would happen when I started out."
