In the wake of Kiwi rider George Bennett crashing into a spectator, world cycling boss Brian Cookson has warned a tragedy is inevitable if fans continue to show reckless behaviour at the Tour de France.
After race favourite Chris Froome's forearm to the face of a Colombian fan who almost knocked him off his bike on Saturday, the Tour de France suffered yet another incident with a spectator overnight when Bennett sent a fan who got in his way sprawling to the tarmac.
Concerns have been raised in recent days about the safety and security of riders in the face of reckless behaviour from fans, with UCI president Cookson telling the London Telegraph that it would not take much for "something tragic" to happen and imploring fans not to get too close to the action.
Froome was fined 200 Swiss Francs by race officials for 'incorrect behaviour' after - in his own words - he "lashed out" at the Colombian fan on Saturday.
Most within the sport, though, sympathised with the Team Sky rider for taking the law into his own hands. As Froome explained afterwards the fan in question had a flag that could have got caught on his handlebars or wheels. Any contact could have been the end of his race. And Froome will certainly have memories of this time last year when he was shouted at, spat at and allegedly had urine thrown at him by roadside spectators.
