Spectator arrested for causing massive Tour de France crash

Three riders since withdrew from the race, according to the organizers.

PARIS -- After a four-day search, a woman was arrested Wednesday as part of the investigation into a large crash at the Tour de France earlier in the week, according to the Brest prosecutor's office. "A woman was arrested in the Finistère today and she is under custody as part of the investigation into the Tour de France incident," the prosecutor's office told ABC News in a statement. "No other information can be shared at the moment: more to come tomorrow." Local police announced on Sunday they were opening an investigation for "manifestly deliberate violation of an obligation of safety or prudence" after a fan caused a large crash by holding a sign in front of cyclists in the opening stage of the competition on Saturday. The woman, who was facing away from the riders, appeared to cause the crash by accident. Tony Martin, a member of top Tour contender Primoz Roglic's Jumbo Visma squad, hit the woman holding the sign on the right side of the road, causing a domino effect for riders inside the peloton.
