A spectator holding a sign that caused a massive crash on the opening day of the Tour de France has been released from custody and charged by French police.

Authorities, eager to protect the identity of the perpetrator, revealed that she is a 31-year-old woman living near Landerneau, where the opening stage ended.

She was arrested Wednesday following Saturday's incident and released Friday morning, according to AFP.

She is charged with two counts, the first being "endangering another person in clear and willful violation of a duty of prudence or safety," and the second being "forcibly inflicting injuries that result in the inability to work for up to three months."

The case will be tried before a Brest court in October and could result in fines of up to €1,500.

However, the women could face further punishment if individuals or groups file their own lawsuits. Race organizers have already dropped their threat to sue, but Movistar's Marc Soler, who left the race with both arms broken, is considering a lawsuit.

Despite the numerous injuries, only Jascha Satterlin has abstained from the Tour as a result of the crash.

On Thursday evening, while the woman was still behind bars, a local prosecutor held a press conference to reveal how she had responded.

According to France Bleue, she was "embarrassed" and "afraid" and "heartbroken at the reaction to the media."

She admitted her "stupidity," but said she needed to "digest the events" before turning herself in to the police. She was also reported to be "psychologically fragile" and "taking this episode very badly."
