AN idiotic fan caused a HUGE crash in the Tour de France.
A fan can be seen holding out their phone to take a photo as a pack of cyclists goes past.
However, Belgium's Nathan van Hooydonck, who was on the edge of the road, hit the fan's extended arm.
This then saw him lose his balance and fall to the floor, proceeding to cause a huge pile-up of an estimated 20 riders during the 15th stage of the tour.
Watching fans rushed to social media to condemn the fan's careless attitude to the event.
One furious fan exclaimed: "I swore out loud."

A second demanded: "It’s about time they started getting prosecuted."
"When will spectators ever learn?! 😡," asked a third.
Then a fourth typed: "Idiot. Why on earth did they think that it was ok to dangle their arm in the peloton WHILE IT WAS GOING PAST?!"
Meanwhile, a fifth added: "Another idiot so-called cycling fan causes a crash taking a photo."

Fortunately, every rider who was down in the crash - which even included former Ineos champ Egan Bernal - is now back on their bike and underway.
It comes after another huge crash in yesterday's stage 14 of the tour, where a number of riders at the back of the peloton were left strewn across the roadside grass following a horrifying pile-up.
Fans hoping for some kind of punishment for the fan may be in luck after the fan who caused a huge crash on stage one of the tour in 2021 stood trial after injuring dozens of riders.
