The spectator who caused a massive pile-up at the Tour de France has been arrested, according to a report by Reuters.
A 30-year-old French woman is in custody after presenting herself at a police station in Landerneau, Brittany, a source close to the investigation told the news agency.
She is accused of involuntarily causing injury and putting the life of others at risk during the opening stage of this year's peloton.
On Saturday, German cyclist Tony Martin was sent tumbling when he rode straight into a cardboard sign being held out by a fan looking the other way at a television camera.
The collision caused a domino effect, wiping out multiple riders in the first stage of the race.
