Usain Bolt was brought crashing down to earth at the World Championships in Beijing – not by rival Justin Gatlin, but a rogue cameraman on a Segway, who ploughed into the back of the Jamaican during his lap of honour.

The entire incident was captured on video.

Bolt got up quickly with a smile on his face, while holding his calf, but reassured everyone he would fit for the upcoming relays.

While his victory over the in-form Justin Gatlin in the 100 meters on Sunday was by a mere hundredth of a second, in the 200 he pounded across the line in 19.55 seconds, almost two tenths of a second ahead of the American (19.74).

Standing in his way of glory is again likely to be two-time drugs cheat Gatlin, whose 19.87secs time was the fastest of the semi-finals. The 29-year-old sprinter was basking in the glory of another gold medal win when a cameraman crashed his party – by crashing into him!

Jobodwana would later relinquish his national record to Van Niekerk, who became the first South African to dip below 20 seconds in the 200m posting a time of 19.94 in July.

He capped his performance with his trademark “Lightning Bolt” pose. “I never doubt that I will win my 200 metres”. As Bolt was celebrating with fans on the outside of the track, a cameraman on a Segway scooter got a little too close for comfort, and disaster struck.

“My four world championship gold medals in the 200 metres, this a big deal, a great accomplishment”.

Christian Taylor, the reigning Olympic champion, leapt to the second-furthest triple jump in history on his final attempt, amassing 18.21 meters from the board, narrowly missing the world record of 18.29 but setting an American record. They were both earned at the 2005 Championships in Helsinki, Finland, where he captured the sprint double to follow up on his 100m gold at the 2004 Olympic Games. Many considered Gatlin the favourite in both events, being undefeated in any race since the 2013 world championships and having run, by wide margins, the fastest times in the world for 2015. Pedro Pablo Pichardo of Cuba took silver at 17.73, also saving his best for the last round.
