Jamaica's Usain Bolt won his third consecutive Olympic gold medal in the 100m with a time of 9.81 seconds.
The 29-year-old, competing in his final Olympics, powered over the line in 9.81 seconds at Rio 2016, vanquishing drug-tainted American rival Justin Gatlin who took silver, with Andre De Grasse of Canada claiming bronze.
The win on Sunday evening at Rio 2016 took the sprinter a step closer to his goal of winning a historic "triple-triple" combination of gold in the 100m, 200m and the 4x100m relay in three consecutive Olympics.
Bolt galloped away in celebration after a superb win, basking in the adulation of the stadium and even taking selfies with fans during his lap of honour.
He then delighted the fans with his traditional "lightning bolt" pose as reggae blasted out of the stadium sound system.
Other than the 2011 world championships, when he was disqualified for a false start, Bolt has won every other global championship individual sprint race since 2008.
That equates to five Olympic golds and seven in the world championships. Throw in two more Olympic and four world championship 4x100m relay golds and the world record in all three events and that is total and utter domination
"This is what we train for. I told you guys I was going to do it," Bolt said,
"Stay tuned, two more to go. Somebody said I can become immortal. Two more medals to go and I can sign off. Immortal."
