Usain Bolt has completed his historic "triple triple" after helping Jamaica to win the 4x100 metres relay at Rio.
Bolt, 29, the fastest man on the planet, has now finished his sweep of 100, 200 and 4x100 metres gold medals at three consecutive Olympics Games.
The runner boasts nine gold medals after Jamaica clocked a time of 37.27 seconds on Friday.
Japan took a surprise silver, while Canada was promoted to bronze after the United States, which came in third, was disqualified.
The disqualification put Team GB in fifth place.
In Jamaica, there were rapturous scenes in response to Bolt's latest victory.
On Monday, Bolt reclaimed his 100 metre Olympic title after winning the final in 9.81 seconds.
Then on Thursday, Bolt won his third 200 metre Olympic gold, clocking a speed of 19.78 seconds, ahead of Britain's Adam Gemili in fourth.
After the race, the Jamaican, who turns 30 at the weekend, said the victory was "beautiful".
"I'm just relieved. I've done it and it's unreal. You never knew from the start that this was going to happen to me, and now it has", he said.
He later paid tribute to fans for their support on Twitter, writing: "You guys never doubted me a min and for that I belong to you guys forever."
