Tour de France leader Vincenzo Nibali knocks away spectator's phone

The issue of fan interference during this year's Tour de France has been magnified by the myriad of "selfies" being taken by onlookers to the dismay of the riders. In fact, many of the cyclists have taken to slapping the phones or cameras directly out of fans' hands if those fans happen to be encroaching on the road.

Even the Tour's leader, Vincenzo Nibali of Italy, has used his share of force to clear oblivious, phone-wielding fans out of his path. Watch the video above as the current yellow jersey wearer throws a shoulder at a fan during her ill-fated attempt to get on camera in Stage 18.

Nibali would go on to win the stage - his fourth - and retain the yellow jersey, which he will secure barring unforeseen circumstances this weekend for his first ever Tour de France victory.
