The Tokyo Olympics were rocked by extraordinary scenes on Monday when half the field false started in the men's triathlon.
The event suffered a rare and embarrassing false start when half the field dived into the water before the other half.
'BONKERS': Swimming world erupts over 'insane' drama
The ones who were left on the pontoon were blocked off by a boat, leading to some frantic action from associated craft to get the message over to the initially unaware swimmers.
Fifty-six men lined up on a pontoon in Tokyo Bay for the 6.30am local start.
But as the starter sent them away for the opening 1500 metre swim leg, around a third found their way blocked by a camera boat.
With those left on the pontoon stranded, a mini-flotilla of boats and jet skis flew into action to head off the group in the water.
More chaos at the troubled Tokyo Games. About half the field false start at the men's triathlon. A speedboat stopped them in their tracks after 150m. Poor officiating from the starter perhaps. Alex Yee and Jonny Brownlee are competing for Team GB pic.twitter.com/MdfXgguur2

Around half of the athletes still ploughed on regardless, despite the alert horn sounding repeatedly.
Eventually two jet skis combined to stop the leaders.
They then returned slowly to the start having undergone a more vigorous 200 metre warmup than they would have liked.
The race eventually got underway safely around 10 minutes later, but the shocking scenes left commentators and fans stunned.
Aussie Olympian Tamsyn Lewis Manou described the start as "insane", while one commentator for BBC said it as a "shambles".
"I've never seen anything like this," he said.
"There was a boat in the way."
A commentator for Channel 7 said: "That is madness."
😮 that was something else! Never seen a triathlon false start, although I did once miss the start and jump in over the boat so they couldn’t stop me from racing 🙊 Come on Jonny! #Tokyo2020 https://t.co/Vek192tHkM
